Alexander Chemeris eeda0e9442 a_reset: Rename SIGTRAN connection to BSSMAP MSC assocation in log messages 
Explanation from Harald:
There are plenty of things that can happen above the bare SCTP/M3UA
connection which can happen, such as SCCP or MTP level routing
problems.

The fact that a MSC responds to a BSSMAP reset tells us that all of
the underlying SS7 transport network is operational and the MSC
responds to us.

Go draw an IP analogy: Saying "SIGTAN connection up" here is like
saying "Ethernet link up" when you get an ICMP response.

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.
