Philipp Maier b9d3c71af3 gsm_08_08: abort complete L3 3 msg gen when no codecs are set 
The COMPLETE LAYER 3 INFORMATION message should contain a Codec List
(BSS Supported) IE. The contents of this list depend on the BTS
capabilities and of the MSC configuration (allowed codecs). There may
be cases where (due to miss-configuration) the list is empty. In those
cases the BSC hits an assertion because the encoding of the overall
message fails when the codec list is empty. A check is needed.

- Check codec list before message generation, abort if the coded
  list is empty.

About OsmoBSC
=============

OsmoBSC originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoBSC was one of the parts split off from the old openbsc.git. Before, it
worked as a standalone osmo-bsc binary as well as a combination of libbsc and
libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A
interface (and IuCS for 3G support) is available, OsmoBSC exists only as a
separate standalone entity.

OsmoBSC exposes
- A over IP towards an MSC (e.g. OsmoMSC);
- Abis interfaces towards various kinds of BTS;
- The Osmocom typical telnet VTY and CTRL interfaces.
