In BSC_Tests_VAMOS.ttcn, in f_est_and_reassign_to_secondary_lchan()
there is a missing channel release ack. By allowing ASP_RSL_UD, this rel
ack can be sent trivially.

BSC_Tests_VAMOS.ttcn is separate from BSC_Tests.ttcn in order to

RSL Channel Activate
RR Immediate Assignment

Without the SMLC routing in place, virtually all BSC_Tests fail with:
VirtSMLC-BSSAP_LE(8)@x42: setverdict(fail): none -> fail reason: "BSSMAP-LE: Timeout waiting for RESET-ACK after sending RESET"
Copy the SMLC part of osmo-stp.cfg from
docker-playground/ttcn3-bsc-test/osmo-stp.cfg and localhost-ize it.

During f_create_chan_and_exp() (part of f_establish_fully()), announce
the BSSAP L3 expectation before activating the lchan.
In RSL_Emulation f_chan_est(), we go through Chan Request, Channel Act
and Immediate Assignment followed by EST IND. Right after that, osmo-bsc
sends a Complete Layer 3 on BSSAP. But in f_create_chan_and_exp(), we
only create the expectation of the BSSAP right after the call to
f_chan_est(), i.e. only after sending the EST IND. So far it was always
juuust in time to work, but when I added a little check to the end of
f_chan_est(), or alternatively an f_sleep(0.2), then BSC tests always
fail with:
Test case TC_reassignment_fr finished. Verdict: fail reason: Couldn't find Expect for incoming connection { [...] pdu := { bssmap := { completeLayer3Information... }
With the BSSAP expectation done first, this error is avoided.

I am introducing a BSC test case that runs through a assigning a TCH
channel for signalling, and then using Channel Mode Modify to change its
mode from signalling to speech. For this to work,
f_channel_needs_modify() needs to actually look up the channel mode of
the TCH and not assume that a TCH is always in speech mode.

CSFB indicator shouldn't be used as stated in the specs. Rather, BSC
should act based on "Last Used E-UTRAN PLMN Id" found in messages such
as Common Id, or Handover Request/Required.

The IE contains a cell list for the MS to register after the channel
is released. The IE is used in CSFB, but not only in that case: it's
also used in SRVCC.
Hence let's remove the CSFB references since the scope is more wide.

It was previously disabled by default in order to avoid test breakage
with older versions of osmocom projects not supporting them. Since we
just did a new release, all -latest contian now master which should work
fine.
Don't remove the moduleparam yet in order to avoid breakage with some

Since Idb453fc894584ccf4f5f8b45a24421db958e9478, osmo-bsc does send
ip.access specific Measurement Pre-Processing Defaults. This message
currently blocks the 'alt' statement in f_recv_next_si1(), so all
test cases calling it fail due to the guard timeout.
What's even worse, both TC_si_acc_rotate() and TC_si_acc_ramp_rotate()
dynamically configure the IUT in order to re-generate and send System
Information messages periodically. If any of them fails prematurely,
the related configuration parameters would remain active, so the IUT
would continue sending System Information messages, causing failures
in subsequent test cases.
Let's simply ignore all unmatched messages in the 'alt' statement.

This test shows that in current osmo-bsc, the start-mode fails to
propagate to the MultiRate Config IE, the only start-mode so far has
always been zero.
Change-Id: I75515baf8cda04567cad8a93c5aa88361c2d259f
Make sure that when a 'start-mode auto' is set, that the previous start
mode setting does not linger in the unused bits.
- after I577ff590d7588fd7e3ee4846c7955ab8f84cf2b1, osmo-bsc sets its
ICMI bit properly, but passes this test only because it *always* sends
smod (start-mode) bits as zero.
- in I49691df01745a7c485bf165e897872c35fc4b147, the smod bits are
properly sent on RSL, but this test shows that when ICMI becomes zero
for 'start-mode auto', the smod bits will remain whatever start-mode
was set in the previous osmo-bsc config. Instead, osmo-bsc should
clear the smod bits for 'start-mode auto' so that its MultiRate Config
does not vary depending on what was previously configured.
- in I1ec5bad0bce01cc425ee05ecf70c83ec662a226a, clearing smod is
implemented and this test is expected to pass.

osmo-bsc currently has a bug that fails to reflect the correct
start-mode in the AMR MultiRate config IE.
And it went unnoticed that the ttcn tests expect a MultiRate config of
ICMI = 1, even though the used configuration should yield ICMI = 0.
See mr_conf = '2804'O, where the '8' indicates ICMI = 1.
As a first fix of the ttcn3-bsc-tests, configure the BSC according to
the expected ICMI value and Start Mode, i.e. ICMI = 1 and StartMode = 0,
which is configured by 'amr tch-[fh] start-mode 1'. This should make
these tests pass as-is for both the current osmo-bsc as well as an
osmo-bsc where the bug is fixed, with minimal changes to the current
tests. See also OS#4868.
An upcoming patch will add tests for 'start-mode auto'.

When a RESET-ACK times out, the logs currently are indistinguishable between
BSSMAP and BSSMAP-LE. Add protocol naming for each RESET / RESET-ACK logging to
make sure the information does not need guesswork.
Example of a test failure shown in jenkins:
BSC_Tests.TC_unsol_ass_compl
Stacktrace
Timeout waiting for RESET-ACK after sending RESET
BSC_Tests.ttcn:8295 BSC_Tests control part
BSC_Tests.ttcn:4274 TC_unsol_ass_compl testcase
Nothing conveys that it is (presumably) the background *BSSMAP-LE* timeout
halting the test 5 seconds in, and not an A-interface failure.

Adding LCS to OsmoBSC creates the possibility of a Paging for LCS, where the
Paging Response should not emit a Complete Layer 3 on the A-interface.
