New fields are put inside a union to keep backward compatibility with
potential older users of the struct.

Some compilers don't like declaration of enums in header files like we
do sometimes for structs:
enum gsm_band;
void foobar(enum gsm_band band);
triggers:
error: use of enum 'gsm_band' without previous declaration

This introduces definitions as well as a parser+encoder for the
Cell Broadcast Service Protocol (CBSP) as specified in 3GPP TS 48.049.
CBSP is used on the interface between CBC and BSC.

We don't really *need* it in libosmocore as such, but the lack of
having all osmocom extensions listed here lead to using overlapping
definitions: 0x18 was used for dynamic PDCH on the Abis side, but also
for CBCH on the L1SAP side. Let's list them all here to increase
visibility in case anyone wants to extend this further...

An enum is more clear than an int and #defines for passing around,
also in case you have a switch () statement, the compiler will issue
warnings for unhandled cases.

Add the constant, so it can be used in create-subscriber-on-demand
related patches. ITU-T Rec. E.164 6.1 states that maximum international
number length should be 15. I did not find a source for a minimum
length, but I've added the constant and set it to 1 for consistency
(based on the existing osmo_msisdn_str_valid() function).

IE GSM0808_IE_OSMO_OSMUX_SUPPORT (T, 1 byte) is sent in AoIP appended to
BSSMAP RESET in order to announce the peer that its MGW supports handling
Osmux streams upon call set up.
IE GSM0808_IE_OSMO_OSMUX_CID (TV, T 1 byte & V 1 byte) is sent in AoIP
during call set up:
* MSC->BSC Assignment Request
* BSC->MSC Assignemnt Complete
The 1 byte value contains the local Osmux CID, aka the recvCID aka CID where the
peer sending the Assign Req/Compl will look for Osmux frames on that
call. Hence, the peer receiving this CID value must use it to send Osmux
frames for that call.
As a result, a given call leg BSC<->MSC can have one different Osmux CID
per direction. For example:
* MS => MGW_BSC ==CID 0==> MGW_MSC
* MS <= MGW_BSC <=CID 1=== MGW_MSC
This allows for setups with 256 call legs per BSC on scenarios where NAT
is not a problem, where MSC can have a pool of 256 CID per MGW_BSC (or
remote peer).

Various places in our code base figure out how many chars they need to safely
store an IMSI. An IMSI can have a checksum digit, which is not reflected by
GSM23003_IMSI_MAX_DIGITS. And we usually need a terminating \0.
Instead of having a magic +2 repeated every so often, rather define
OSMO_IMSI_BUF_SIZE to contain both checksum digit and nul char, and have the
explanatory comment with it here in libosmocore.

We have a habit of returning static buffers from some functions,
particularly when generating some kind of string values. This is
convenient in terms of memory management, but it comes at the expense
of not being thread-safe, and not allowing for two calls of the
related function within one printf() statement.
Let's introduce _c suffix versions of those functions where the
caller passes in a talloc context from which the output buffer shall
be allocated.

As per 3GPP TS 03.40, section 9.2.3.16 "TP-User-Data-Length (TP-UDL)"
field may contain up to 140 octets (or 140 * 8 / 7 = 160 septets).

We have a number of static buffers in use in libosmo*. This means
the related functions are not usable in a thread-safe way. While
we so far don't have many multi-threaded programs in the osmocom
universe, the static buffers also prevent us from calling the same
e.g. string-ify function twice within a single printf() call.
Let's make sure there's an alternative function in all those cases,
where the user can pass in a caller-allocated buffer + size, and make
the 'classic' function with the static buffer a wrapper around that
_buf() variant.

The function gsm0808_sc_cfg_from_gsm48_mr_cfg() takes an S15 to S0
bitmask and converts that bitmask into an AMR multirate configuration
struct.
Unfortunately the current implementation implements 3GPP TS 28.062,
Table 7.11.3.1.3-2 wrongly in some aspects. Lets fix this.
- Fix wrong interpretation of the bitpatterns
- 5,15K is invalid and must never be selected
- Make sure that no more than 4 rates are selected in the active set
- Extend unit-test
