Philipp Maier a9b9276948 gsm0808: add default speech codec configuration
In an AoIP scenario, the speech codec list field specifies the
codecs used in the RTP interface. This patch adds a table
with default codec configurations that match the codec
configurations that are also used on the air interface.

Philipp Maier bb8396690e gsm0808: fix AoIP speech codec element parser/generator
The implementation of the parser/generator for the speech codec
information element slightly wrong, making it impossible to use
it properly.

Philipp Maier da38203418 gsm0808: add speech codec type constants
The codec type to be set in member type in struct gsm0808_speech_codec
has its own coding scheme to reference the used codec types. This patch
declares an enum with valid speech codec types.

Daniel Willmann 6959e3c110 gsm_04_08: Add missing GSM cause value
Table 10.5.157 in 10.5.6.6 of 3GPP TS 04.08 is badly formatted. The first
value 0x19 "LLC or SNDCP failure" is in the same line as the heading and has
not been included in the struct_value so far.

Table 10.5.157 in 10.5.6.6 of 3GPP TS 24.008 fixes this formatting issue and
also defines two more values 0x08 and 0x18 which are now added to the struct
value_string.

* function to serialize it into msgb
* function to deserialize it from buffer
* functions to extract/estimate buffer size for SW Description
* test harness (partially taken from OpenBSC)

There are several similar functions to deal with SW Description in
OpenBSC, there's also need to use similar functionality in
OsmoBTS. Hence it's better to put the code into common library with
proper tests and documentation.

Neels Hofmeyr 00ab9ed6e2 add gsm48_pdisc_msgtype_name()
Composing the message type string requires knowing the protocol discriminator.
To ease printing the message type, add this function to switch between the
defined value_string[]s depending on pdisc.

Also publish the message type value_string[]s -- without inline functions to
access them because it is anyway more convenient to use
gsm48_pdisc_msgtype_name() instead.

Since gsm48_pdisc_msgtype_name() is nontrivial, do not add as inline function
-- in case the message type is not known, it needs a static string buffer.

The previous version of this commit got reverted to avoid a breakage in openbsc.
The problem is openbsc use an array of chreq_type with a manual defined size. This array
is using enums as index which breaks if any elements got added into the
middle, because the size of the array can't hold elements greater or
equal than the size.

Neels Hofmeyr d1c2fc6de1 gsm_04_08.h: add R99 MSCR and CBQ3 to SI3 Ctrl Chan Descr
MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE
of SI3.

Assuming that no-one is using the spare bits, this will not cause any code
conflicts.

In the R99 struct, spare1 and spare2 are in different places, so rather rename
them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone
tries to use them with the wrong structure.

Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by
TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section
10.5.2.11, so drop the explicit reference.

Motivation: the R99 Control Channel Description defines MSCR to indicate
whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to
indicate that our libmsc is capable of R99, like OsmoSGSN already does.

CBQ3 is merely added for completeness, no particular use case in mind.

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.
