By default systemd will execute service with root directory (or home directory for user instance) which might result in
attempts to create files in unexpected place. Let's set it to 'osmocom' subdir of state directory (/var/lib for system instance) instead.

As part of preparation for libosmo-netif migration let's move common SMPP code
into separate build-time library and use it for both smpp_mirror and OsmoMSC
renaming the files if necessary.
While at it we also fix id/password legth limits in smpp_mirror and drop unused
fields from ESME struct.

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.

This is meant as a safeguard against users or user equipment which

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.

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
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.

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.

If the ESME has been disconnected (dead socket) but still is
in memory (other users hold a use count), we shouldn't enqueue
messages to the write queue.

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.

The function vlr_subscr_rx_imsi_detach() implies that an explicit IMSI
DETACH was received. However, that same function was called in other
situations such as timer expiration or GSUP CANCEL.

No logical change is introduced to the VLR in this patch.

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
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.

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.

RAT-side connection of the call leg after having properly sent
VND.3GPP.IUFP/16000 in CRCX.
