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 any bearing on the tests besides more accurately showing
RTP stream setup in the logs.

Use either the SDP or the Bearer Capabilites indicated in the incoming
MNCC to apply the remote call leg's codecs selection to the codecs
filter. Use the codecs filter result for outgoing Bearer Capabilites.
So far, we just forwarded the Bearer Capabilities received in MNCC from
the remote call leg, and omitted Bearer Cap if the remote call leg did
not provide any.
Instead, always include Bearer Cap, and compose it from the codecs
filter result. Hence the Bearer Cap is now an intersection of MS, BSS
and remote call leg, instead of just the remote call leg.

When the HLR fails to return auth info and authentication and ciphering
are configured to be optional, fall back to no-auth.

Add third outcome of auth_fsm: the no_auth_info_event, which should be
dispatched when auth failed because the HLR has no auth info for this
subscriber, i.e. not because an actual auth challenge failed.
No functional change: Handling no_auth_info_event separately follows in
another patch (to allow fallback to no-auth). Feed the same
_E_AUTH_FAILURE as no_auth_info_event to still behave unchanged.

Explicitly send distinct parent events on auth success and failure. So
far determining success depended only on the data pointer passed on with
the event. Distinct events clarify the logging and the FSM code.
This prepares for a third FSM outcome to be added in a subsequent patch,
to separately signal when the HLR has no auth data.
No functional change.

Since call_leg_fsm_releasing_onenter() calls immediatelly
osmo_fsm_inst_term(), it meant we couldn't receive any event in that
state because osmo_fsm disables event dispatching to FSMs being
terminated.
As a result, CALL_LEG_EV_MGW_ENDPOINT_GONE was never received and hence
call_leg_mgw_endpoint_gone() was never called, which means the
mgcp_client used in cl->mgw_endpoint was never put back to the pool.
By first freeing all the children (rtp_streams), we make sure
cl->mgw_endpoint ends up with no conns and sends us the GONE event
before we go ourselves into termination state.

Large RAN installations may benefit from distributing the RTP voice
stream load over multiple media gateways.
libosmo-mgcp-client supports MGW pooling since version 1.8.0 (more than
one year ago). OsmoBSC has already been making use of it since then (see
osmo-bsc.git 8d22e6870637ed6d392a8a77aeaebc51b23a8a50); lets use this
feature in osmo-msc too.
This commit is also part of a series of patches cleaning up
libosmo-mgcp-client and slowly getting rid of the old non-mgw-pooled VTY
configuration, in order to keep only 1 way to configure
libosmo-mgcp-client through VTY.

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.

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.

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.

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.
