Neels Hofmeyr f0ff9a6711 fix dyn TS init: properly identify BTS on OML OPSTART ACK
Commit "dyn ts, bts_ipaccess_nanobts.c: init PDCH on Chan OPSTART ACK"
bf7099262a Icf6e25ff068e8a2600562d52726ead65e864ec02
introduced signal S_NM_OPSTART_ACK and passed the FOM header to identify the BTS
by. But the FOM header's BTS number is zero on each Abis/IP link, and the BTS
and TRX are actually identified by msgb->dst == e1inp_sign_link, member trx. So
the initial implementation associated *all* Channel OPSTART ACKs with BTS 0.

Pass the entire msgb as S_NM_OPSTART_ACK signal argument, implement a
abis_nm_get_ts() to retrieve the proper timeslot and use that during timeslot
init.

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.
