Introduce gsm0808_dec_cell_id_list2() with supports additional types of
cell identifier lists. The new parsing routines are based on similar
routines used by the paging code in osmo-bsc's osmo_bsc_bssap.c.
Likewise, introduce gsm0808_enc_cell_id_list2() with support for the
same additional types of cell identifier lists.
The old API using struct gsm0808_cell_id_list is deprecated.
The previous definition was insufficient because it assumed that all
decoded cell ID types could be represented with a single uint16_t.
It was declared in a GSM protocol header (gsm/protocol/gsm_08_08.h)
despite being a host-side representation of data in an IE.
The only user I am aware of is in osmo-msc, where this struct is used
for one local variable. osmo-msc releases >= 1.1.0 make use of this API.
While here, fix a small bug in a test:
test_gsm0808_enc_dec_cell_id_list_bss() set the cell ID type to 'LAC'
but obviously wants to use type 'BSS'.

octet are *not* part of the message type in any of the L3 protocols
which implement sequence numbers. it doesn't matter if it's R98 or
R99, or whether the sequence number is 1bit or 2bits wide.

Considering the various styles and implications found in the sources, edit
scores of files to follow the same API doc guidelines around the doxygen
grouping and the \file tag.
Many files now show a short description in the generated API doc that was so
far only available as C comment.
The guidelines and reasoning behind it is documented at
https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation
In some instances, remove file comments and add to the corresponding group
instead, to be shared among several files (e.g. bitvec).

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.

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.

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.

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
