Change the unit_id value, that is supposed to be unknown at BTS, from
0/0/0 to 42/0/0 to make TC_oml_unknown_unit_id pass again. The test was
failing, because a new bts that matches 0/0/0 was added to osmo-bsc.cfg
in [1], [2] and [3].

The way how the TITAN support for DIAMETER works, is that there's
an awk-based shell script and lots of DIAMETER dictionaries in the
https://github.com/eclipse/titan.ProtocolModules.DIAMETER_ProtocolModule_Generator
repository.
I've used 'AVP.sh Base_IETF_RFC3588.ddf BaseTypes_IETF_RFC3588.ddf
AAAInterface_3GPP_TS29272_f10.ddf GxInterface_PCC_3GPP_TS29212_f10.ddf
S6Interfaces_3GPP_TS29336_f00.ddf MobileIPv6_HA_IETF_RFC5778.ddf
RxInterface_PCC_3GPP_TS29214_f20.ddf' to generate the DIAMETER_Types
file we use here.
DIAMETER is used as signaling protocol between the HSS and other core
element nodes in the EPC, such as the MME and S-GW.

The TTCN3 tests MSC_Tests.TC_bssap_lu_sgsap_lu_and_mt_call and
MSC_Tests.TC_sgsap_lu_and_mt_call initate an MT-CSFB call for testing
purposes, but they also send an SGsAP-MO-CSFB-INDICATION to make the MS
come back to LTE. This is wrong. SGsAP-MO-CSFB-INDICATION just informs
the VLR that the UE has initiated a MO CSFB call on the LTE side. On MT
CSFB calls this message should not appear. Lets remove it.

The testcase TC_paging_resp_unsol expects the BSC to close the channel
when an unsolicit paging response is received. This expectation is due
to the fact that osmo-bsc supports multiple MSC, which is not specified
in 3gpp specs. Therefore the BSC needs to know which MSC is in charge.
However, with MT-CSFB calls it is a normal situation that the BSC
receives a paging response on abis without sending a paging first since
the MSC has paged the UE via the SGs interface. In those cases we expect
the BSC to forward the paging response to the first configured MSC.

So far, the RAN_Emulation only supported the CS domain, and not PS. Let's

It originally seemed like a great idea to define a custom record
which aggregates the decoded BSSGP, LLC, L3 and/or SNDCP and passes
it to the individual ConnHdlr. However, particularly with testcase
interoperability for IuPS in mind, this seems bogus. Also, we
never really took advantage of this.
Let's now decode as far as we can decode any PDU, and then send the
decoded version of that PDU via the ports between the BSSGP_Emulation
and the ConnHdlr component.

Since osmo-bsc commit "neighbor config: allow re-using ARFCN+BSIC pairs"
(I29bca59ab232eddc74e0d4698efb9c9992443983), osmo-bsc considers only those
cells as neighbors that are explicitly listed, or all local cells if none are
listed. This lead to breaking TC_ho_int, because the osmo-bsc.cfg has only one
remote-cell neighbor for bts 0, and hence a handover to local cell bts 1 is now
regarded as invalid.
The remote-cell neighbor is needed for inter-BSC handover tests; also consider
that the TC_ho_neighbor_config_* tests each place individual neighbor
configuration by live VTY interaction.
Hence make all of these tests more robust: remove the neighbor config from the
osmo-bsc.cfg file, and instead include VTY interaction for each test case that
sets the particularly needed neighbor configuration at runtime.
An analogous osmo-bsc.cfg change in docker-playground is in change
If44dd6b578cdc55076c8180707d1c2d69fe5f2a8.
(It is not actually harmful to leave the neighbor config in osmo-bsc.cfg, but
remove that since it is also not needed anymore.)

Since [1] we additionally filter Access Bursts by the link quality
(defined by C/I) in L1SAP, and since [2] we do provide the actual
C/I values for osmo-bts-trx, as was received from the transceiver.

The default minimum C/I for Access Bursts in OsmoBTS is 50 cB,
while the TTCN-3 test cases configure fake_trx.py to send 0 cB,
so all Access Bursts are getting dropped, as expected.
Let's use 60 cB (or 6 dB) by default. This change makes Access
Bursts pass again, and thus fixes some broken test cases.

The idea of this test case is to verify that the link quality
measurements, in particular C/I (Carrier-to-Interference ratio),
are delivered to the PCU (as a part of PCUIF_DATA.ind).
The C/I ratio needs to be calculated by the transceiver from the
training sequence of each burst, where we can compare the "ideal"
training sequence with the actual training sequence and then
express that in cB (centiBels).
This test case can only be executed with fake_trx.py and trxcon,
because this pair allows us to simulate C/I values. Also, the
new TRXD header format needs to be supported (see OS#4006).

Extend BSC_ConnHdlr with new check IMEI related parameters. Add tests
for check IMEI and check IMEI early for multiple auth variations, as
well as variants where the HLR would respond with NOK or ERR.
Note that we can safely set "check-imei-rqd 0" in f_init(), because the
latest OsmoMSC version already suppors this VTY command.
Two tests do not always pass, sometimes the RAN connection breaks
before the test finishes (TC_lu_imsi_auth_tmsi_check_imei_err and
TC_lu_imsi_auth_tmsi_check_imei_nack). I have added them as expected
errors in the expected-results.xml.

Make sure that the RR is released only after the MSC has sent the Clear Command:
- first expect a Clear Request from osmo-bsc and return a Clear Command,
- only then accept RR release messages.
See 3GPP TS 48.008 3.1.5.3.3 "Abnormal Conditions": "The terrestrial resource
in the old BSS shall remain assigned until a CLEAR COMMAND message is received
from the MSC"
osmo-bsc already complies, the test should continue to pass.
