Vadim Yanitskiy 570b4c8be2 libmsc/db.c: get rid of hard-coded SMS expiry threshold 
The initial idea of the SMS expiry threshold was to avoid storing
SMS messages with too long validity time (e.g. 63 weeks).
Unfortunately, neither this feature was properly documented, nor
the expiry threshold is configurable. Moreover, it has been
implemented in a wrong way, so instead of deleting the oldest
expired message, it would delete the youngest one or nothing:

  SELECT ... FROM SMS ORDER BY created LIMIT 1;

while it should be sorted by 'valid_until' in ascending order:

  SELECT .. FROM SMS ORDER BY valid_until LIMIT 1;

Thus, if the oldest message is expired, it gets deleted. If the
oldest message is not expired yet, there is nothing to delete.

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.
