Prepares for the unit test, which can now simply check for encode/decode
identity.

In the process, also:
* Change the license from AGPLv3 to GPLv2-or-later;
* correct spelling of 'sysmocom' to lowercase;
* add '2016' to the copyright;
* rename to osmo_*;
* add API docs;
* add logging category DLOAP: define id and add to internal_cat;
* redirect all oap.c logging to DLOAP.
A unit test will follow in a subsequent patch, since it needs a minor tweak for
decoding of boolean values.

All DL* categories are typically negative, but DLGSUP isn't, and it's also not
in libosmocore's internal_cat array.
See: 3b6fb0880c3ab1e23a3d7d738d073b00c2a794c2
This means that a program using DLGSUP has to include DLGSUP in its own logging
cat array (typically not needed for DL* categories), which means for osmo-nitb
that DLGSUP (11) replaces DMGCP (also 11), and DMGCP becomes unusable.
Fix this: make DLGSUP -11 and include in internal_cat.
In gsup_test.c, no longer add DLGSUP to the logging categories array.
External follow-ups are otherwise needed only in osmo-hlr.git and some pending
patches for openbsc (Id3938267fa062e1a997d3704cd678874306f86ee).

Add missing doc string for the HOSTNAME arg.
Added in commit aa00f99be2e4cc64ede20d8c9548b83054696581, this breaks the VTY
tests for openbsc and hence breaks our jenkins build jobs.

Often it is useful to have log statements from the osmocom programs
synchronized with protocol traces. So rather than having to open the
pcap file with GSMTAP or other protocol data side-by-side with the
textual log of one or more network elements, we simply pass the log
lines around as GSMTAP messages, which can then be displayed in-order
and interspersed with the protocol messages inside wireshark.

truncating the unsigned long pointer msg->data to 'int' and then passin
git into msgb_resize_area() is unsafe as depending on the 32rd address
bit it will be eiether negative or positive. That will in turn change
the expected "Sub area is not fully contained in the msg data\n" error
message into "Negative sizes are not allowed\n" which is not what the
autotest case expects.

The G used to mean GPRS, but the scope is larger now. To satisfy the curious
reader, give the G a name in gsup files' header comments. BTW, logging.h and

In gsup.c/h's copyright notice, 'sysmocom' should be spelled lower case.

The write queue was always meant to not queue more than the
max_length messages but the implementation never rejected a
message.
Begin to log and enforce the queue size limit, add a testcase
to verify the code and initialize except_cb as part of a fix
for that new test case.
Real applications might now run into the queue limit and drop
messages where they just queued them before. It is unfortunate
but I still think it is good to implement the routine as it was
intended. We need to review osmo_wqueue_enqueue once more to
see that no msgb is leaked.

Some targets might not want to receive only an opaque, pre-formatted
string, but rather the unformatted arguments with metadata like
sub-system/level/file/line. We solve this by introducing a
log_target->output_raw() function pointer. If a target specifies this
function, it takes precedence over the regular log_target->output()
function.

CHREQ_T_PDCH_TWO_PHASE"
This reverts commit c3c28528de78fd5d50c3a141c2176c0da5dd7075.
The reason is that this breaks a static assert in openbsc.
See https://lists.osmocom.org/pipermail/openbsc/2016-December/009906.html
Enlarging the ctype_by_chreq struct and breaks the static assert for
gsm_network->ctype_by_chreq's size:
../../../src/libbsc/gsm_04_08_utils.c:138:1: error: size of array ‘dummyassert_size’ is negative
osmo_static_assert(sizeof(ctype_by_chreq) ==
^
What this patch lacks is, in openbsc.git:
* adjustment of ctype_by_chreq[] according to the new additions in
libbsc/gsm_04_08_utils.c
* same for reason_by_chreq[], also in libbsc/gsm_04_08_utils.c
* enlarge ctype_by_chreq[] in gsm_network to 18, in openbsc/gsm_data.h.
Leaving it up to the original authors to follow up and commit a complete patch
series in one go.

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.

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.

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
gsm_08_58.h

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.
