Merge branch 'master' into sysmocom/iu, with tweaks

Numerous manual adjustments are included to make sense on the sysmocom/iu branch:

* gsm_04_08_gprs.h has moved to libosmocore on the master branch, but
  sysmocom/iu has added some entries. Until it is clear whether to move the
  additions to libosmocore as well, keep gsm_04_08_gprs.h on sysmocom/iu with
  merely the additions.
* Thus, keep using the old gsm_04_08_gprs.[hc] from openbsc in the Makefiles,
  but only where the sysmocom/iu additions are needed.
* In openbsc's gsm_04_08_gprs.h,
  * include the libosmocore gsm_04_08_gprs.h,
  * use '#pragma once' instead of #ifndef and
  * add a TODO comment about moving the rest to libosmocore.

* Apply the addition of an osmo_auth_vector to gsm_auth_tuple: in the Iu auth
  vector hacks, use the gsm_auth_tuple.vec instead of a local struct.
  See iu_hack__get_hardcoded_auth_tuple() and gsm48_rx_gmm_att_req().

* In the si2q tests, pass NULL as ctx to gsm_network_init().

* In cscn_main.c, add a debug log that was originally added to osmo-nitb.

* openbsc/.gitignore: keep only one addition of 'writtenconfig'

-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.
-
-The libosmo-mgcp library exposes MGCP server utilities used by e.g. OsmoBSC-NAT
-(found in osmo-bsc.git) to navigate RTP streams through a NAT.
-(At time of writing, this is still called libosmo-legacy-mgcp.)

-# ===========================================================================
-#   http://www.gnu.org/software/autoconf-archive/ax_check_compile_flag.html
-# ===========================================================================
-#
-# SYNOPSIS
-#
-#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
-#
-# DESCRIPTION
-#
-#   Check whether the given FLAG works with the current language's compiler
-#   or gives an error.  (Warnings, however, are ignored)
-#
-#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
-#   success/failure.
-#
-#   If EXTRA-FLAGS is defined, it is added to the current language's default
-#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
-#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
-#   force the compiler to issue an error when a bad flag is given.
-#
-#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
-#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+About OpenBSC
+=============
+
+OpenBSC started as a minimalistic all-in-one implementation of the GSM Network,
+with particular emphasis on the functionality typically provided by the BSC,
+MSC, HLR, VLR and SMSC.  Today it is a growing suite of libraries and programs,
+implementing protocol stacks and functional elements, including
+
+ * OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC
+ * OsmoBSC-MGCP - MGCP helper to the OsmoBSC software
+ * OsmoNITB - a BSC+MSC+VLR+HLR+SMSC "Network in the box".
+ * OsmoCSCN - a voice CN with A/IP and IuCS/IP towards the BSC and/or HNB-GW
+ * OsmoSGSN - a GPRS SGSN with Gb/IP and IuPS/IP towards the PCU and/or HNB-GW
+ * Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN
+ * OsmoBSCNAT - a gateway aggregating many A links as one A link to the MSC
+ * OsmoGTPHUB - a hub aggregating many GTP links (between SGSN and GGSN)
+ * ipaccess-utils - some tools to discover + configure ip.access nanoBTS
+ * bs11_config - a tool to configure the Siemens BS-11 microBTS
+
+Various interfaces towards the BTS are supported, among which are:
+
+ * Classic A-bis over E1 using a mISDN based E1 interface. In other
+   words, you can connect existing GSM Base Transceiver Station (BTS)
+   through E1 to OpenBSC.  So far, we have made it work with the Siemens BS-11,
+   various Ericsson RBS2xxx BTS models and the Nokia MetroSite.
+
+ * A-bis over IP as used by the ip.access nanoBTS product family as well as
+   the Open Source OsmoBTS software (by the same authors as OpenBSC).  OsmoBTS
+   in turn supports various transceiver hardware, including the sysmoBTS
+   product family, as well as SDR transceivers supported by OsmoTRX, such as
+   the UmTRX or USRP boardss.
+
+ * IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G)
+   voice and data links.

+This is an incomplete collection of call graphs between MSC and Osmo-BSC,

+towards the BSC, and have an Iu-CS interface to operate with HNB-GW and hNodeB.
+The working title for the result is Osmo-CSCN (Circuit Switched Core Network),
