Harald Welte 2765a18450 sms: Make default SMS validity period configurable via VTY

Harald Welte e6f1160046 smpp: Parse and use SMPP-provided validity period
Before this patch, we always ignored any SMPP-provided validity period
and used '0' which is now, and means it expires immediately.

As SMPP allows for validity_period of NULL, use 7 days as SMSC default
in such situations.

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.

Harald Welte 1d72e301cb db: Switch from 'synchronous = FULL' to 'synchronous = NORMAL'
As we're using WAL mode, it is not neccessary to use synchronous=FULL
but rely on synchronous=NORMAL mode while still guaranteeing database
consistency.

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

See https://www.sqlite.org/pragma.html#pragma_synchronous for the
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.

When the SMPP code free's an ESME it also free's the related write_queue
and the osmo_fd contained therein.  So if this happens while we are
in esme_link_read_cb(), we must return -EBADF to make
osmo_wqueue_bfd_cb() of libosmocore avoid further accessing related
memory.

Harald Welte 467fc5728d switch sqlite3 to single-threaded mode
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.

Neels Hofmeyr 5d53c6001d fix crash on CM Serv Rej: fix use count mismatch
With comments, clarify the code paths where a CM Service use count has
not yet been placed on the conn (just send CM Service Reject) and where
the use count is placed (decrement count on CM Service Reject).

Place the CM Service use count slightly earlier:
- it is then correctly present when checking the mobile identity in
  cm_serv_reuse_conn(), avoiding the crash reported in OS#5532.
- there is only one place incrementing the use count instead of two.

Pau Espin 9de384a28c Avoid setting audio codec if not available during assignment_complete (MDCX)
RAB Assignment Complete contains no codec info, hence
assignment_complete.codec is not set and
assignment_complete.codec_present is false.
As a result a wrong value is passed to rtp_stream_set_codec.

This fixes osmo-msc sending "a=rtpmap:112 AMR/8000/1" during MDCX in the
RAT-side connection of the call leg after having properly sent
VND.3GPP.IUFP/16000 in CRCX.

Alexander Couzens e400b1161d ran_msg_iu: do not pass UEA0 to ranap_new_msg_sec_mod_cmd2()
On the protocol level, it's impossible to indicate UEA0 together
with the other algorithms.  The encryption is either a) disabled,
so the Encryption Information IE is not present, or b) enabled,
so the Encryption Information IE indicates UEA1 and/or UEA2.

Because of that, the ranap_new_msg_sec_mod_cmd2() would fail to
generate the RANAP PDU if the given bitmask has the UEA0 bit set.

Vadim Yanitskiy c44342b88c libmsc: fix memory leak (struct msgb) in msc_i_ran_enc()
Function msc_i_ran_enc() calls msc_role_ran_encode(), but unlike the
other callers of this function it does not free() the encoded message.

A simple solution would be to call msgb_free(), like it's done in
the other places.  But a more elegant solution is to modify function
msc_role_ran_encode(), so that it attaches the msgb to OTC_SELECT.
This way there is no need to call msgb_free() here and there.

This change fixes a memleak observed while running ttcn3-msc-test.
