Added configuration parameter GSM.Authentication to OpenBTS config database. It allows enable or disable authentication.
Now we have 3 modes of operation for authentication and encryption:
1. Authentication enable, encryption enable.
2. Authentication enable, encryption disable.
3. Authentication disable, encryption disable.
1. Implemented AuthenticationParameters class for easy storage and using authentication parameters: MobileID, SRES, RAND, CKSN and KC.
2. Added functions for registerIMSI and authenticate to MobilityManagement.
3. Added authentication procedure to LocationUpdatingController.
4. Modified sip_register function in SIPMessage, added IMSI, SRES, RAND parameters to support authentication.
5. Modified Register and unregister functions in SIPEngine, added AuthenticationParameters.
6. Added new configuration parameter GSM.Encryption to OpenBTS config database. It allows enable or disable encryption.
1. Added functions for encryption and decryption activation and setting KC and CipherID to GSMLogicalChannel.
2. Added functions for encrypt, decrypt, setting KC and CipherID to L1Encoder, L1Decoder and L1FEC.
3. Implemented decrypt and encrypt for XCCHL1 Decoder and Encoder, TCHFACCH Decoder and Encoder.
4. Added xor_apply function to BitVector and SoftVector.
5. Added libosmocore and libosmogsm dependences for using osmo_a5 and osmo_hexparse functions.
CommonLibs: Avoid direct syslog calls in ConfigurationTable
We instead introduce a 'log early' facility in Logger.h to accomplish

I added similar code to the reporting functions, which did not exist when sylvain made this patch

Patch 4588 in private:
For some reason, ReportingTest won't build on all systems. Since it is not part of the actuall application, I am commenting it out from the Makefile.am for now.

The adaptive energy detection threshold does not scale relative
to signal level. In other words, the adjustment factor will be
the same whether the at 40% of signal level or 4%. If the receive
gain is reduced by a large amount, suppose 20 dB, the receiver
may take minutes to adjust to the new level.
When the receive gain is changed, reset the threshold back to
the initial level. This reduces issues of runtime gain adjustment
and prevents blocking bursts while the threhold level slowly
adjusts.

1)I did an experiment and compiled OpenBTS with clang yesterday, which
immediately highlighted two potential bugs in the Transceiver52 code.
I'm not sure they are indeed bugs and not the intended behavior, but
they look very much like that. The first one is below and the second
one is in the following mail.
GSM::Time() arguments are defined like #define USB_LATENCY_INTRVL
(10,0), which means that they are expanded into GSM::Time((10,0)).
This expression is a GSM::Time() with a single parameter where (10,0)
return value of the last argument, 0 in this case. I.e.
GSM::Time((10,0)) is equivalent to GSM::Time(0). I think this was not
the intention.
2) Printing \n after every complex number breaks output when you want to
print it in a single line, e.g. in many debug output.
I do not claim any copyright over this change, as it's very basic.
Looking forward to see it merged into mainline.

Check for transceiver with a "ping", not be waiting for the clock.
The fixes in the socket class seem to have solved this problem.

Add a few SIP message fixes. Add function that may be used for accepting out of order 200 and 487 messages.
Note that some of this was pushed earlier for compilation reasons

r4232: Major change in hos entries are removed from a TransactionTable.
>From now on, the only place were entries are actually removed is in TransactionTable::innerRemove.
Anywhere else, the remove methods just set a flag to tag the entry for later removal be innerRemove.
This allows us to survive situations where we try to touch transactions that have been removed already. We still log at the ERR level, but no more segfaults.
Updated all of the TransactionTable "find" methods to not return pointers to dead or removed tranactions.
Updated find-by-channel search to return the transaction entry with the highest transaction number, which fixes a bug that sometimes picked up the wrong transaction records during EA TCH assignment.
r4253: New exception class for when someone tries to use a "removed" transaction.
r4254: Updated copyright notice.
r4265: Unlock TransactionEntry::mLock while blocked on SIP message FIFOs in SIPEngine. This does wonders to reduce lock contention and make everything more snappy.
Use Mutex::tryLock in TransactionEntry::dead and if lock is held, assume that it is not dead. This also does a lot to reduce lock contention.
r4294: Change Um congestion response back to SIP 503.
r4295: When deleting an entry that has failed to respond to paging, send a SIP 480 response so the switch knows that transaction is dead.
r4412: Fixed bug that was causing SIPInterface to crash when the IMSI cannot be extracted from the To: header.

This patch makes a step towards using a system-wide sqlite3 lib. It
moves sqlite3util.cpp/.h to CommonLibs and leaves only original
sqlite3 files in the sqlite3 dir of OpenBTS.
