The most interesting information is which result the codec filter ends
up with. So print the resulting codec intersection first, add the filter
stages after that.

I noticed by chance that the Assignment Complete message generated in
the test lacks a remote RTP address for the RAN side.
Make the test more realistic by adding a remote RTP address and port. It
doesn't have much bearing on the tests, though.

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.

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.
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.

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.

Calling gsm48_cc_tx_release() before mncc_release_ind() has a side
effect: the former may change CC state to GSM_CSTATE_RELEASE_REQ.
This makes the later send MNCC_REL_CNF instead of MNCC_REL_IND, so
if one of the call leg disconnects due to RF failure, the other one
will not be terminated correctly.
Makes both TC_{mo,mt}_call_clear_request TTCN-3 test cases pass.

The msc_vlr_tests verify whether any of the tests run contain msgb or
talloc memory leaks. So far they did so by fixating a specific number of
talloc blocks, which may break by library implementations changing.
Instead, verify that the test leaks no allocations by comparing talloc
blocks before and after each test.
When a leak is detected, print the full talloc report to stderr, which
makes the expected output mismatch the actual output and fails the test.

This patch served for a manual testing counterpart for osmo-bsc to implement

Since the split of OsmoNiTB, OsmoMSC does not deal with the radio
access network directly. Therefore the only purpose of T3212 is to
control subscriber expiration in the local VLR. The timeout value
indicated in System Information Type 3 needs to be configured
separately in the BSC/RNC.
This means that we don't need to store it in deci-hours anymore.
Let's move T3212 to the group of VLR specific timers, so it can
be configured and introspected using the generic 'timer' command,
and deprecate the old '[no] periodic location update' command.
It should be also noted that in the old code subscriber expiration
timeout was actually set to twice the T3212 value plus one minute.
After this change, we apply the configured value 'as-is', but
keep the old behaviour for 'periodic location update' command.

In order for osmo-hlr to be able to 100% guarantee distinct INDs for CS and PS,
set CN-Domain = CS in all SendAuthInfo Requests.
In Milenage auth, it is highly desirable that osmo-hlr guarantees use of
distinct INDs for CS and PS domains. If an MSC and SGSN attached at the same
time use the same IND bucket to generate Milenage SQN, that collision would
rapidly waste SQNs and load osmo-hlr with requesting new auth tuples on each
CS/PS Complete-Layer3.
So far, osmo-msc did not indicate the CN domain in the GSUP SendAuthInfo
Request, which was neither required nor evaluated. The CN-Domain is only sent
for the UpdateLocation Request that usually follows later.

Substantial parts of the CC / MNCC call establishment were so far completely
missing from the msc_vlr_test_call.c tests. With my new insights on CC and MNCC

Root reason: since I am going to re-order the sequence of events to enable
codec negotiation via SDP in MNCC, I want to have comprehensive tests of the CC
procedures to see the effect as diffs in the test output.

We sometimes see errors like
libmsc/msc_a.c:361 msc_a(...){MSC_A_ST_RELEASING}: transition to state MSC_A_ST_RELEASING not permitted!
i.e. changing state to the state msc_a is already in.
Ignore re-entering the same state for most state changes. However, there is one
state change in msc_a where re-entering the MSC_A_ST_VALIDATE_L3 is necessary
to start the timeout.
Hence add msc_a_state_chg_always() and use that for re-entering
MSC_A_ST_VALIDATE_L3. Change msc_a_state_chg() to skip no-op state changes.
This should silence all no-op state change error messages for msc_a.

To not break the msc_vlr tests by new GSUP IEs added to some of the GSUP
messages, make msc_vlr_tests only match the start of the GSUP message and not
care about extra IEs. The extra IEs are anyway seen in the expected logs.
The reason to drop the msgb_eq_data_print() is because it is useless for
mismatching lengths. It will always print only the length mismatch, instead we
need to be able to compare with what was expected.
