Neels Hofmeyr c9e0ca3d1f sdp_msg: add sdp_audio_codecs_cmp(), add compare flags
A problem with SDP fmtp handling is visible in this patch: when cmp_fmtp
is true, we compare fmtp strings 1:1, which is not how things should be
done. The intention is to fix fmtp handling in a later patch.

At least there now is a flag to bypass fmtp comparison altogether.

Harald Welte 1a62db20e7 sms: Give smsc its own VTY config node
The pre-historic sms_queue code used to have very strange aspects,
such as having some parameters (max-failure, max-pending) which could
only be sent from the 'enable' node, but not from a config file.

Before adding more configuration parameters, let's clean this up by
introducing a proper VTY config node for the 'smsc'; move the existing
config commands there and add new ones for max-failure and max-pending.

As the sms_queue data structure is only allocated after the config file
parsing happens, we are introducing a new 'sms_queue_config' data
structure.  This encapsulates the public readable/writable config
parameters.

As we're using WAL mode, it is not neccessary to use synchronous=FULL
but rely on synchronous=NORMAL mode while still guaranteeing database

To do this, we can fix the typo in one of our two PRAGMA statements,
and remove the other.

sqlite3 documentation on that topic.

Harald Welte d43c22ef65 switch from libdbi to lbsqlite3
The choice of libdbi was one of the biggest early mistakes in (back
then) OpenBSC development.  A database abstraction library that
prevents you from using proper prepared statements.  Let's finally
abandon it and use sqlite3 directly, just like we do in osmo-hlr.

I decided to remove the database migration code as it would be relatively
cumbersome to port all of it to direct sqlite3 with prepared statements,
and it is prone to introduction of all kinds of errors.  Since we don't
have a body of older database files and comprehensive migration tests,
it is safer to not offer migration code of uncertain quality.  The last
schema revision (5) was introduced 5 years ago in 2017 (osmo-msc
v1.1.0), so it is considered an exceptionally rare case.  People can
install osmo-msc 1.1.0 through 1.8.0 to upgrade to v5 before using
this new 'direct sqlite3' version of osmo-msc.

Looking at 'perf top' of osmo-msc under load shows that there's a
significant amount of time spent in terms of locking (mutex,...)
which is useless as osmo-msc is a single-threaded application.

Unfortunately libdbi doesn't provide a mechanism to perform
sqlite3_config(), so we have to do it directly here, introducing an
explicit build-time dependency (and linkage) to libsqlite3.

With comments, clarify the code paths where a CM Service use count has

Place the CM Service use count slightly earlier:
- it is then correctly present when checking the mobile identity in

- there is only one place incrementing the use count instead of two.

Vadim Yanitskiy 565ea2ba0c libvlr: fix is_ciph_required(): always send SecModeCmd for UTRAN
Ciphering is optional in both GERAN and UTRAN, however for the later
it's *required* to enable integrity protection for the signalling.
Thus we must always send Security Mode Command in UTRAN, even in
case if ciphering is disabled (UEA0) in the configuration.

The actual decision whether to send CMC/SMC or not is taken in:

  * vlr_access_req_fsm.c / _proc_arq_vlr_node2(), and
  * vlr_lu_fsm.c / vlr_loc_upd_post_auth().

depending on the value returned by is_ciph_required().  Let's
rename this function to is_cmc_smc_required() and ensure that
it always returns true in UTRAN.
