It's better if we run ttcn3-bts-test with the default values, given
that they were significantly reduced some time ago.

Otherwise it's impossible to run the CBSP test cases locally, because
the remote peer address in osmo-bsc gets set to '0.0.0.0', so indeed
it cannot establish connection to the server.

It's clearly stated in a comment to this function that the returned

Using the same IMSI in each test case makes it harder to correlate
subscriber connections in the SUT with particular test cases. A
good example is a problem described in OS#5337: some test cases
create dangling subscriber entries that never got released:
OsmoBSC# show subscriber all
IMSI TMSI Use
001019876543210 ffffffff 3 (3*paging-start)
001010000100001 ffffffff 1 (conn)
With this patch I am getting the following output:
OsmoBSC# show subscriber all
IMSI TMSI Use
001016017428234 ffffffff 1 (paging-start)
001014631230680 ffffffff 1 (paging-start)
001011161500382 ffffffff 1 (paging-start)
001010000100001 ffffffff 1 (conn)
so I was able to correlate the following test cases:
* (001016017428234) TC_lcs_loc_req_for_active_ms_ta_req,
* (001014631230680) TC_lcs_loc_req_for_active_ms_le_timeout2,
* (001011161500382) TC_cm_service_during_lcs_loc_req,
* (001010000100001) TC_no_msc.

The resulting set of dependencies needed just to have one simple CellId
struct is huge. That was fine for sgsn testsuite since anyway those were
being used, but it's not acceptable for other testsuites (hnodeb) which
only really require the GTP side.
After this change, GTP_Templates only requires GSM_Types, which ends up
in a much smaller subset of dependencies being pulled in.

This change fixes sporadic failures of TC_cm_serv_rej:
RAN Connection table not found by component TC_cm_serv_rej(2648)
BSC_Tests.ttcn:11106 BSC_Tests control part
BSC_Tests.ttcn:10550 TC_cm_serv_rej testcase
The reason is that sometimes a BSSAP/DTAP PDU (with CM Service Reject)
gets enqueued before the SUT has established an SCCP connection to the
virtual MSC. This causes a lookup error in the RAN connection table.
A simple solution would be to add a receive statement after calling
f_create_chan_and_exp(), like it's done everywhere else:
f_create_chan_and_exp();
BSSAP.receive(tr_BSSMAP_ComplL3); // <---
But a more general solution is to expect and receive this message in
f_create_chan_and_exp(), so we can reduce code duplication and make
the API more convinient. This is exactly what this change does.

The idea is to generate a talloc report after execution of a test
case and store it together with PCAP files. This might be useful
for detecting memory leaks and finding the relevant test cases.
To enable this feature, make sure that osmo_interact_vty.py from
osmo-python-tests is installed (see [1]), and the following
variables are set (see [2]):
* OSMO_SUT_HOST (e.g. "127.0.0.1"), and
* OSMO_SUT_PORT (e.g. 4242).

A new Iuh CodecPort + Emulation is introduced to (de)mux RANAP and RUA
in the same SCTP socket.
The Iuh_CodecPort.ttcn file has currently a hack to be able to test
HNBAP, since titan seem to be reporting sinfo_ppid=0 when in fact it
received sinfo_ppid=20 (HNBAP).
A couple tests are added to validate HNBAP HNBRegister Request + Accept
or Reject. In current osmo-hnodeb state, both tests pass if run
separately, but fail if run sequentially since osmo-hnodeb still doesn't
re-connect properly after first test finishes and connection is dropped.

So far all handover tests trigger handover via VTY command. This means
that any bugs introduced in measurement report handling and handover
target selection are by definition not caught.
Almost a year ago, fixing a handover oscillation bug for intra-BSC
handover introduced a segfault for inter-BSC handover targets, because
for those the target.bts is NULL. Show this bug.

Due to the migration to a multithreading scheme the timing behavior of
the stats items has slightly changed. There is now a 1 sec update cycle
in which the stats items are regenerated. This means we have to wait 1
sec. before we can query the endpoints.used stats item.

As can be seen from ttcn3-bsc-test run #1565 on Jenkins [1], it may
happen that the VTY command requesting handover reaches the IUT earlier
than the SCCP 'SACK CC' message. In this case, the 'SUBSCR_CONN' FSM
remains in state 'WAIT_CC', so we get an error:
(bts=0,trx=0,ts=0,ss=0) (ARFCN 871) --> BTS 1 Manually triggering Handover from VTY
SUBSCR_CONN(msc0-conn204)[0x5633b2877af0]{WAIT_CC}: Received Event HANDOVER_START
SUBSCR_CONN(msc0-conn204)[0x5633b2877af0]{WAIT_CC}: Event HANDOVER_START not permitted
The easiest way to avoid this is to introduce and artificial delay
after the connection establishment and before triggering the handover.

I cannot reproduce the issue in my local system with docker, probabluy
due to different performance from jenkins builder. It triggers almost
every time in jenkins nightly TTCN3 PCU_tests though.
A similar fix was already introduced recently for TC_n3105_max_t3195
since PCU started submitting empty (idle) blocks when there's no TBF
listening on that PDCH. We need to update the test to account for that,
since our TTCN3 timers are not necessarily exactly matching the one at
the PCU side.
