Add two functions to create USSD messages. Moves and generalizes code from
openbsc. Pending: use the new functions in openbsc.
It looks like _release_complete() should also set trans_id and direction flag;
but since this is moving code from openbsc that is apparently working, just
place a fixme comment and don't change the functionality.

Add function gsm0480_l3hdr_push() to push a struct gsm48_hdr to the start of a
msgb. Use in gsm0480.c and gsm0411_utils.c. Further callers of the new function
will follow in openbsc as well as another libosmocore patch for ussd.

The 'strtok_r' function requires passing a NULL as the first parameter
on subsequent calls in order to ensure the code picks up where it left
off on a previous call. However, Coverity doesn't quite realize this
and points out that if a NULL was passed in as the third argument it
would result in a possible NULL deref because the strtok_r function will
assign the third argument to the first in the call is NULL.

I'm aware of the existing criticism on stlrcpy(), but I think it is
still better than what we have now: stnrcpy(), sometimes with Coverity
warnings and sometimes with a manual setting of the termination byte.
The implementation follows the linux kernel strlcpy() which is claimed
to be BSD compatible.
We could of course link against libbsd on Linux instead, but I think
it's reasonably small and simple to provide our own implementation.
Future versions of libosmocore could use some autoconf magic and
preprocessor macros to use the system-provided strlcpy() if it exists.

gsm48_encode_bcd_number() can theoretically return a length in excess of
the size of the bcd_buf, but only in case an overly-long IMSI is passed
into the function (which would be illegal in the first place).

Numerous issues caused sim_test to be attempted even though libosmosim was not
built:
In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported.
Furthermore in configure.ac, no value 'yes'/'no' was assigned to the
ENABLE_PCSC variable, only to the enable_pcsc value.
In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have
no effect, regardless (not even when using a variable that should be defined
accurately).
So fix with these steps, similarly to how we do it in openbsc:
In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'.
Export the same using AC_SUBST().
Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add
atlocal to AC_OUTPUT and distclean).
Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to
indicate skipping the test if enable_sim_test isn't 'yes'.

Ericsson uses non standard information element tags when setting
up the SI13 system information configuration. This applies to
RSL_SYSTEM_INFO_13, which is normally 0x28, instead Ericsson
uses RSL_ERIC_SYSTEM_INFO_13, which is set to 0x0C. Furthermore,
Ericsson adds a propritary field called BCCH-Mapping, which is
tagged as 0xf2 (RSL_IE_ERIC_BCCH_MAPPING)
This patch addes these two information element tags in

This is an actual bug. If we recevied a BSSGP Paging Request without
P-TMSI, we might crash or report some random memory as P-TMSI to the
caller in the output data structure.

As outlined by mail on the 13th of July the tree based approach to
decoding in the PCU is faster by order of magnitude. Instead of having a
slow implementation in the library and a quick one in the PCU, let's
only have a quick one in the PCU and at some point in the future move it
to libosmocore.
Execute the plan and remove t4_decode.

Instead of generating every convolutional code into a separate
file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to
have a single file, containing all definitions, because as many
convolutional codes we add, as many entries we will have to add
into 'src/gsm/Makefile.am'. This approach increases readability
of the Makefile.am, and also makes us able to share some data
between some convolutional code definitions.
For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use
the same *_state[][2] and *_output[][2] arrays within a single
file. This optimization is currently WIP.

--enable-sanitize adds address sanitizer CFLAGS/CPPFLAGS to the entire build.
Also pass UBSAN_OPTIONS to the test suite run (only has effect during runtime).
Add this flag to jenkins.sh's configure step. To ensure that we get the
sanitize results, add 'make check' to jenkins to catch sanitize failures;
Keep 'make distcheck' without ASAN; it has its own configure which omits
--enable-sanitize. This way we test both with and without ASAN.

See 04.80[1], section 3.4: the highest two bits are used as counter or ignored
and do not contribute to the SS "Miscellaneous message group". Previous mask of
0xbf included the highest bit, fix to 0x3f.
Observed a value of 0xbb that should mean 0x3b="Register" during testing of 3G
USSD requests, which seem to be the first to send a nonzero highest bit to our
code. The erratic mask of 0xbf lead to an unhandled message type of 0xbb.
