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.

* data structure representing 3GPP TS 52.021 §9.4.62 SW Description
* 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.

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.

I often want to log the protocol discriminator in the openbsc debug log. It's
more useful to get the name directly instead of looking it up every time.

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.

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.

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.

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

Using the RSL_CHAN_* constants, we sometimes need to add 1 to the chan bits
to indicate e.g. the second TCH/H channel.
RSL_CHAN_NR_1 marks this lowest channel bit that needs to be added.
The name is analogous to RSL_CHAN_NR_MASK.

Add inline functions for both release <= 98 and release >= 99 as well as a
default define. Use the release 98 by default since the current code base uses
the r98 bitmasks.
These inline functions relieve callers of the decision on masking bits of the
protocol discriminator and message type octets.
Also add a define for the protocol discriminator extension to one octet length
(GSM48_PDISC_EXTEND).
