The altstep as_handover needs to repeat until the IPACC and the MGCP rtp
negotiation is done (MDCX). By setting the norepeat flag of the sub
altsteap as_Media_mgw to true, we allow as_handover to exit early, even
when the handover is not done yet, which eventually causes the testcase
to fail.

According to 3GPP TS 44.018, table 10.5.2.21.1 "Mobile Allocation
information element", in the cell allocation frequency list the
absolute RF channel numbers are placed in increasing order of ARFCN,
except that ARFCN 0, if included in the set, is put in the last
position in the list.
Let's verify that the IUT handles this corner case correctly.

The Mobile Allocation IE generated by the IUT includes not only
the list of hopping ARFCNs, but also ARFCN of the transceiver
itself. This is the correct behaviour, and that's why we see
sporadic test case failures like this one:
Mobile Allocation IE does not match (tn := 1):
{ len := 3, ma := '001010101011111100000000'B }
vs expected
{ len := 2, ma := '0010101010111111'B }
The last '0'B bits may look like redundant padding, but actually
only 7 of them are. The MSB '0'B bit in the last (third) octet
corresponds to pre-configured ARFCN 871.
Since f_TC_fh_params_gen() generates all ARFCNs in GSM-900:
- in f_TC_fh_params_gen(), pick an ARFCN value from GSM-900;
- in f_TC_fh_params_set(), change ARFCN of a given transceiver;
- in f_TC_fh_params_gen_tr_ma(), consider that ARFCN;
- in f_TC_fh_params_unset(), bring it back to 871.

This record must contain not only the hopping parameters, but
also ARFCN of the transceiver they belong to. Since ARFCN of
the transceiver also becomes part of the Mobile Allocation,
we need to take it into account in the matching functions.

This scenario appeared in jenkins runs of BSC_Tests making
TC_ctrl_msc_connection_status fail (the first test in the suite). I
could however not reproduce it on my local docker setup because it
really seems like a timing race condition.
The scenario is:
TTCN3 -> BSC: RESET
TTCN3 <- BSC: RESET
TTCN3 -> BSC: RESET-ACK
In there, TTCN3's f_legacy_bssap_reset() expected a RESET-ACK to be
received, but it may well be that the other end never saw the RESET and
hence it will never sent the RESET-ACK, since it indicated it became
available afterwards. In that case (RESET received), let's not fail if a
RESET-ACK is never received, since the connection is actually in the
desired state and this scenario can happen and it's all fine.

My initial assumption was that we can skip redundant '0'B bits or
even '00'O octets in the Mobile Allocation IE, and thus reduce
the overall size of this element. Unfortunately, this is wrong.
3GPP TS 44.018, section 10.5.2.21 clearly states that the Mobile
Allocation IE contains a bit-string of size NF, where NF is the
number of frequencies in the cell allocation. If NF % 8 != 0,
then '0'B padding bits must be appended to make it octet-aligned.
In other words, if the cell allocation contains let's say 13
frequencies, but a hopping timeslot makes use of only a small
fraction of it (e.g. 4 first channels), we would still need to
transmit at least 13 bits (+padding), including all redundant
bits and octets.

so the CBCH channel vanishes after this test case is executed.

Some tests may stop without cleaning up the CBSP state. Avoid affecting
subsequent tests by clearing the state for each f_cbsp_init_server().
Some ETWS CMD may still be left in the RSL queue (from the time period passing
between a stopped test and the next test starting up), so clear all RSL ports.
To be able to do so, move f_cbsp_reset_bss() to the cbsp_test_CT, from where it
can access both CBSP and IPA_RSL[] ports. All current callers are on
cbsp_test_CT anyway.
This patch should fix TC_cbsp_emerg_write_bts_cgi_cchan and
TC_cbsp_emerg_write_bts_cgi_cchan_disable, which so far break because of
leftover ETWS CMDs in the RSL queue from the preceding test run.

For each CBSP test, define one global set of CBSP msg id and serno for use by
that test.
Each CBSP test should use a distinct message id and serial nr, to not get mixed
up with previous state. But keeping those numbers manually is a confusing pain,
and as a reader it is hard to follow how these numbers change (if they do).
In f_cbsp_init_server(), require a preset of msg id and serno to be used in
that test, and from then on only use g_cbsp_msg_id and g_cbsp_ser_no instead of
magic numbers. If they change, write it out explicitly, making it easy to
follow what is expected to happen, and also making it easy to copy-paste code
snippets without having to manually adjust magic numbers.
Choice of numbers: pick a simpler scheme where both msg_id and ser_no share a
common "prefix" in the 1000s range, and for a ser_no add 500 to keep distinct
numbers (that avoid confusion when reading the logs):
test prefix msg_id ser_no next-ser_no
1 1000 1001 1501 1502
2 2000 2001 2501 2502
3 3000 3001 3501 3502

Recently fixed errors in the last_block counting as well as encoding ask for a
proper test coverage of various lengths, which also verifies the expected
blocks count explicitly.
Implement this in TC_cbsp_write_bss():
Run f_tc_cbsp_write_bss() multiple times with differing fixed payload lengths,
at all block count transitions, plus some arbitrary lengths in-between.
Before this patch, TC_cbsp_write_bss() would pick a different random payload
length for every test run, which, until recently, then sporadically hit
last_block value errors. That's not good for reproducability.
