Neels Hofmeyr 665d48bf15 cosmetic: gsup comments: write 'Generic' for the G in GSUP
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
gsup_test.c already mentioned "Generic" before this.

The copyright in gsup.h differed from the one in gsup.c: gsup.c names the GNU
Affero GPL, gsup.h only the GNU GPL. Change both to GPL-v2-or-later.

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

Neels Hofmeyr 909cbecbb9 Revert "gsm0408: add chreq_type for CHREQ_T_PDCH_ONE_PHASE and CHREQ_T_PDCH_TWO_PHASE"
This reverts commit c3c28528de.

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.

Neels Hofmeyr bc1d758299 gsm0480: add gsm0480_create_ussd_notify() and *_release_complete()
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.

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.

Philipp Maier 00b1539007 RSL: Add defines for ericsson systinfo SI13
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
