Pau Espin c84702c571 Change default SCTP conn NULL->127.0.0.1 to localhost->localhost 
"127.0.0.1" is changed to "localhost" to let local NSS decide whether to
use IPv4 or IPv6. In newish systems, IPv6 ::1 will be selected since
IPv6 takes precedence over IPv4.

Similarly, the default source addr needs to be changed from NULL to "localhost"
since for some yet unknwon reason, getaddrinfo(AF_UNSPEC, NULL) returns
first IPv4 "0.0.0.0" and later "::", which is inconsistent with
getaddrinfo("localhost") result, resulting in src=IPv4(0.0.0.0) and
dst=IPv6(::1), which is incompatible and will fail. In any case, since
the default remote address is a local one and it's the client side,
there's no real logical change since the kernel would anyway should have
taken a local address anyway.

About OsmoMSC
=============

OsmoMSC 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.

OsmoMSC was one of the parts split off from the old openbsc.git. Before, it was
the libmsc part of the old OsmoNITB. Since a true A interface and IuCS for 3G
support is available, OsmoMSC exists only as a separate standalone entity.

OsmoMSC exposes
- GSUP towards OsmoHLR (or a MAP proxy);
- A over IP towards a BSC (e.g. OsmoBSC);
- IuCS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G voice;
- MNCC (Mobile Network Call Control derived from GSM TS 04.07);
- SMPP 3.4 (Short Message Peer-to-Peer);
- The Osmocom typical telnet VTY and CTRL interfaces.
