Harald Welte c0f0007292 import oap message parsing / encoding from openbsc.git; AGPL->GPL
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.

Vadim Yanitskiy d2d9760c08 utils/conv_gen.py: generate a single file
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.

Neels Hofmeyr a95ee5e6e1 fix USSD: SS message type mask should be 0x3f, not 0xbf
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.

This is a "flag" day change. Old OpenBSC break with new libosmocore
because suddenly there is the 0x in front. I am afraid we need to
find a better solution here. I think we will need to create a
gsm48_mi_to_string variant that takes a mode parameter to enable the
TMSI mode and deprecate the old method.

Right now we should not break old versions of OpenBSC.
