Use libosmo-netif instead of socket interface.
Note: osmo_stream_srv_recv() is not used for now to keep as much of existing
code as possible and make troubleshooting easier.

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.
While at it we also fix id/password legth limits in smpp_mirror and drop unused
fields from ESME struct.

This is meant as a safeguard against users or user equipment which
doesn't set a reasonable validity period. Using this setting, the
SMSC administrator can set a minimum SMS validity period. Any SMS
submitted with lower validity period will be extended to that minimum.

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,

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

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

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.

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.

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.

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.
This change fixes the Iu test cases in ttcn3-msc-test.
