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.

- Add missing message types to be up to date with the
latest specification release (3GPP TS 04.18)
- Add value strings to translate RR message type identifiers
into human readable strings. (see gsm48_rr_msg_name() in
gsm48.h

rr_cause_name() is located a far of from
value_string rr_cause_names[] while other value string
functions are located right below their related value
string definitions. This commit moves rr_cause_name()
below rr_cause_names[] as it should be

This is a "flag" day change. Old OpenBSC break with new libosmocore
because suddenly there is the 0x in front. I am afraid we need to
find a better solution here. I think we will need to create a
gsm48_mi_to_string variant that takes a mode parameter to enable the
TMSI mode and deprecate the old method.
Right now we should not break old versions of OpenBSC.
This reverts commit 78ad042f94.

Previously, we traditionally displayed a TMSI in its integer
representation, which is quite unusual in the telecom world.
A TMSI is normally printed as a series of 8 hex digits.

For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/
gsm48_decode_lai(). Those functions also handle a trivial extra
member (lac) which I don't need in this way for 3G.
So create new functions to take on the MCC+MNC BCD handling and call those
from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code
in openbsc can use only the BCD functionality without code duplication.
This information element has been added to the MM Information
message in GSM24.008. This patch adds it to the tlv_definition
to keep the TLV parser from breaking.

The &buf[3] is unlikely to be aligned properly. Use memcpy instead
of an assignment. Add a small testcase that verifies that I didn't
mess up the conversion.

This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.
This has been proposed by Harald Welte and Sylvain Munaunt.
Tested with `make distcheck'.

I have also moved generate_backtrace() to backtrace.c instead
of gsm_utils.c, otherwise the timer and msgfile tests depend on
libosmogsm.
