Version bump for testing it on the target

The adding of the innocent looking code was actually overwrote
the fd and then stupid things happened. Rename variables to avoid
that. rc,ret should be scratch variables...

-About OsmoMGW
-=============
-
-OsmoMGW originated from the OpenBSC project, which started as a minimalistic
-all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
-maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
-IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
-approach to fully independent separate programs as in typical GSM networks.
-
-OsmoMGW was one of the parts split off from the old openbsc.git. It originated
-as a solution to merely navigate RTP streams through a NAT, but has since
-matured to a Media Gateway implementation that is capable of streaming RTP for
-2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time
-of writing) transcoding between TRAU, various RTP payloads and IuUP.
-
-The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and
-OsmoBSC, and receives and sends RTP streams as configured via MGCP.
-
-The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found
-in osmo-msc.git) to instruct OsmoMGW via its MGCP service.
-

-== Configuring OsmoMGW
-
-A basic configation of OsmoMGW mainly consists of specifying the IP address
-and port on which to listen to MGCP commands, but changing the port range at
-which the RTP streams terminate as well as limiting operation to a single call
-agent can be done as well as changing the number of endpoints.
-
-=== Configuring MGCP
-
-By default OsmoMGW listens for MGCP on port 2427 on any IP address. If a call
-agent address is configured then OsmoMGW will only answer MGCP commands from
-that IP port 2727, otherwise all sources are handled. A domain can be
-specified
-
-.Example: MGCP configuration
-----
-OsmoMGW(config-mgcp)# bind ip 127.0.0.1
-OsmoMGW(config-mgcp)# bind port 2427
-OsmoMGW(config-mgcp)# call-agent ip 127.0.0.1
-OsmoMGW(config-mgcp)# domain mgw-bsc
-OsmoMGW(config-mgcp)# local ip 127.0.0.1
-----
-
-=== Configuring the trunk
-
-The first trunk (trunk 0) is considered a virtual trunk in OsmoMGW. All
-endpoints of type "rtpbridge" are routed here. The virtual trunk is configured
-in the config-mgcp context.
-
-All other trunks are configured in the config-mgcp-trunk context, but the
-commands used are identical. Right now trunks are considered only for ds/e1
-type endpoints which are not yet implemented. Don't use trunks other than the
-"virtual" trunk 0.
-
-.Example: MGCP trunk configuration
-----
-OsmoMGW(config-mgcp)# number endpoints 63 <1>
-OsmoMGW(config-mgcp)# rtp bind-ip 10.0.0.1 <2>
-OsmoMGW(config-mgcp)# rtp port-range 12000-14000 <3>
-----
-<1> Maximum number of endpoints that can be allocated at once
-<2> Use this IP when binding RTP endpoints
-<3> Use ports in this range when binding RTP endpoints
-
-There are some options to tweak how RTP forwarding behaves in OsmoMGW:
-
-.Example: MGCP trunk rtp options
-----
-OsmoMGW(config-mgcp)# rtp keep-alive 30 <1>
-OsmoMGW(config-mgcp)# rtp-patch ssrc <2>
-OsmoMGW(config-mgcp)# rtp-patch timestamp <3>
-----
-<1> Send dummy UDP packets periodically to RTP destination
-<2> Hide SSRC changes
-<3> Ensure RTP timestamp is aligned with frame duration

-== MGCP Extensions
-
-The MGCP protocol is extendable. The following non-standard extensions are
-understood by OsmoMGW.
-
-=== `X-Osmo-IGN`
-
-`X-Osmo-IGN` indicates to OsmoMGW that specific items of an endpoint should be
-ignored, so that it is lenient on mismatching values that would normally
-indicate collisions or configuration errors.
-
-==== `X-Osmo-IGN` Format
-
-The value part of `X-Osmo-IGN` must be one or more items separated by one or more
-spaces. Each item consists of one or more non-whitespace characters.
-
-.Example: `X-Osmo-IGN` format with three ficticious items "X", "abc" and "123".
-----
-X-Osmo-IGN: X abc 123
-----
-
-`X-Osmo-IGN` must be issued in the MGCP header section (typically as its last item),
-before the SDP section starts.
-
-==== Supported `X-Osmo-IGN` Items
-
-Currently, the following `X-Osmo-IGN` items are supported:
-
-* `C`: ignore CallID mismatches, i.e. differing "C" values between connections
-  on the same endpoint.
-
-.Note:
-`X-Osmo-IGN` does not support ignoring mismatches on the domain part of
-an endpoint name, e.g. ignoring a mismatch on "example.com" in
-`rtpbridge/123abc@example.com`. Instead, you may globally configure OsmoMGW
-with `mgcp` / `domain *` to permit all domain parts.
-
-===== `X-Osmo-IGN: C`
-
-By default, OsmoMGW verifies that all CallIDs ("C" values) match for all
-connections on any one given endpoint. To ignore CallID mismatches, pass a `C`
-in the `X-Osmo-IGN` header, for the first or the second `CRCX` on an endpoint.
-When the `X-Osmo-IGN: C` is sent for any one `CRCX` on an endpoint, CallID
-mismatches will be ignored for that and all subsequent messages for that
-endpoint. Hence this header only needs to be included once per endpoint, in any
-`CRCX` message that precedes or coincides with a CallID mismatch.
-
-This is particularly useful for a BSC that is connected to an A/SCCPlite MSC,
-where the BSC and MSC each are expected to configure their respective own
-connection on a shared endpoint. For A/SCCPlite, it is impossible for the BSC
-to know the CallID that the MSC will use, so CallID mismatches are inevitable.
-See also OsmoBSC, which will by default pass the `X-Osmo-IGN: C` header for
-endpoints associated with an A/SCCPlite MSC.

-== Overview
-
-This manual should help you getting started with OsmoMGW. It will cover
-aspects of configuring and running the media gateway.
-
-[[intro_overview]]
-=== About OsmoMGW
-
-OsmoMGW is the Osmocom implementation of a media gateway to handle user
-plane (voice) traffic in cellular networks. It can connect and optionally
-transcode RTP voice streams between different network elements such as BTSs
-and external entities like SIP. It is typically co-located with both OsmoBSC
-and OsmoMSC and controlled by them via MGCP, the Media Gateway Control
-Protocol.

-=== Software Components
-
-OsmoMGW contains a variety of different software components, which we’ll
-quickly describe in this section.
-
-==== MGCP Implementation
-
-OsmoMGW brings its own MGCP implementation through which OsmoMGW is
-controlled.
-
-The commands implemented are CRCX, MDCX, DLCX and RSIP. The command AUEP is
-implemented as a stub and will simply respond with OK.
-
-==== RTP implementation
-
-Support for IuUP which is used in 3G cells is quite lacking at the moment.
-3G<->3G and 2G<->2G calls should work, but 3G<->2G does not.
-
-==== Audio transcoder
-
-Transcoding is currently not supported in OsmoMGW.
-
-=== Limitations
-
-Osmux is not yet supported in OsmoMGW.
-
-At the moment (July 2018), OsmoMGW only implements RTP proxy / RTP bridge
-type endpoints, to each of which two RTP connections can be established.
-We are planning to add endpoint types for:
-
-- classic E1/T1 timeslots (64kBps alaw/ulaw)
-- classic E1/T1 16k sub-slots with TRAU frames for classic BTS support
-- announcement/playout end-points
-- conference endpoints
-
-=== Additional resources
-
-You can find the OsmoMGW issue tracker and wiki online at
-
-- https://osmocom.org/projects/osmomgw
-- https://osmocom.org/projects/osmomgw/wiki
-
-RFC 3435 for MGCP is located at
-

-== Running OsmoMGW
-
-The OsmoMGW executable (`osmo-mgw`) offers the following command-line
-arguments:
-
-=== SYNOPSIS
-
-*osmo-mgw* [-h|-V] [-D] [-c 'CONFIGFILE'] [-s]
-
-=== OPTIONS
-
-*-h, --help*::
-	Print a short help message about the supported options
-*-V, --version*::
-	Print the compile-time version number of the program
-*-D, --daemonize*::
-	Fork the process as a daemon into background.
-*-c, --config-file 'CONFIGFILE'*::
-	Specify the file and path name of the configuration file to be
-	used. If none is specified, use `osmo-mgw.cfg` in the current
-	working directory.
-*-s, --disable-color*::
-	Disable colors for logging to stderr. This has mostly been
-	deprecated by VTY based logging configuration, see <<logging>>
-	for more information.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+ * This code derived from a leaked document from the GSM standards.
+ * Some missing pieces were filled in by reverse-engineering a working SIM.
+ * We have verified that this is the correct COMP128 algorithm.
+ *
+ * The first page of the document identifies it as
+ * 	_Technical Information: GSM System Security Study_.
+ * 	10-1617-01, 10th June 1988.
+ * The bottom of the title page is marked
+ * 	Racal Research Ltd.
+ * 	Worton Drive, Worton Grange Industrial Estate,
+ * 	Reading, Berks. RG2 0SB, England.
+ * 	Telephone: Reading (0734) 868601   Telex: 847152
+ * The relevant bits are in Part I, Section 20 (pages 66--67).  Enjoy!
+ *
+ * Note: There are three typos in the spec (discovered by
+ * reverse-engineering).
+ * First, "z = (2 * x[n] + x[n]) mod 2^(9-j)" should clearly read
+ * "z = (2 * x[m] + x[n]) mod 2^(9-j)".
+ * Second, the "k" loop in the "Form bits from bytes" section is severely
+ * botched: the k index should run only from 0 to 3, and clearly the range
+ * on "the (8-k)th bit of byte j" is also off (should be 0..7, not 1..8,
+ * to be consistent with the subsequent section).
+ * Third, SRES is taken from the first 8 nibbles of x[], not the last 8 as
+ * claimed in the document.  (And the document doesn't specify how Kc is
+ * derived, but that was also easily discovered with reverse engineering.)
+ * All of these typos have been corrected in the following code.
