The test sets random bits for SI5 and expects to see those in dl SACCH. That
can only possibly work when that SI5 was actually sent to the BTS.

Previous commit implemented the CS/MCS verification, and hence now some
tests fail because they had too restrictive checks.
In theory the verifications could be done so restrictive by configuring
the PCU accordingly at the start of the test, but we are not
really interested in checking the exact CS/MCS in these tests, only
checking if GPRS/EGPRS is being used.

Let's provide this information to higher layer since CS is mostly
discovered by original bitstring size which is available during
decoding.
Call the size2mcs converter in each function to avoid having to pass it
as a parameter and have it selfcontained, meaning one can simply call
decode(bitstring) from TTCN3 code and be done with it.

Once GPRS/EGPRS multiplexed support is ready, it will be controlled
through pcu info_ind.flags by enabling
MCS or not; the "egprs only" VTY comamnd will be dropped.
The usual setup would be to support both GPRS+EGPRS, so make that the default.
Most tests require to be passed the _noMCS variant to work in older
versions of PCU, since those versions use the "egprs only" concept which
will reject egprs_ms_class=0. Same tests enabling MCS in newer osmo-pcu
shouldn't be a problem.

Similar to the DL TBF counterpart from last commit, this time verifying
UL multislot TBF is allocated.
Change-Id: I26a3cc0f2bd7bab176aa52df3e40aca7300de216
ARFCNs are allocated sequentially, so that conversion between
arfcn<->trx_nr is easily done.
Some helper functions are introduced to be able to submit and expect
messages on a given TRX+TS, which is required for setups with several
TRX and PDCH-enabled TS different than the default. These new APIs
will be used in PCU_Tests.ttcn in subsequent patches.

The change introduces three new test cases:
- TC_paging_cs_multi_ms_imsi,
- TC_paging_cs_multi_ms_tmsi,
- TC_paging_cs_multi_ms_imsi_tmsi.
Each of these establishes 56 Uplink TBFs, and then enqueues 56 CS
PAGING requests from the SGSN side. The main idea is to verify
encoding and compositing of the paging MIs in PACCH massages.

We never launch this test case in DTX mode on anything else than
TCH/F, so it does not make sense to check this all the time.

There is no such thing like a fill frame on SACCH:
- on Downlink, it's always System Information messages;
- on Uplink, it's always the Measurement Reports.
Yes, osmo-bts-trx does send dummy LAPDm func=UI frames on SACCH,
but this happens because the test suite never feds it with the
associated System Information messages (i.e. Type 5, 5ter, 6).
In the 'alt' statement, restrict matching of L1CTL DATA.ind, so
only DCCH/FACCH blocks are counted. Ignore DL SACCH blocks.
This change reveals that TC_tch_sign_l2_fill_frame_dtxd actually
fails because no fill frames are received at all from the IUT.

In TTCN-3, array assumes a fixed number of elements. A 'record of'
type is more like a 'list' in Python, so let's call it this way.

older versions of osmo-pcu were broken and were only allocating TBFs in
the first TRX available. This is now fixed and hence osmo-pcu tries
better to allocate TBFs across different TRX. That's why the test needs
to be fixed to set up only 1 TRX in order to run into the same scenario.

TTCN-3 offers templates and pattern matching, so no need to match
against all possible variants of the RSL channel number.

The current definition of the SI2quater Rest Octets is incomplete.
In particular, the missing part is Repeated UTRAN FDD/TDD Neighbour
Cells structure, for which 3GPP came up with a very tricky encoding.
Given that both test cases checking scheduling of the SI messages
and not their content, let's simply use different SI2quater samples
containing E-UTRAN Parameters Description instead.

The current TC_meas_res_speech_tchX tests only test a pure voice
transmission. A voice transmission can be occasionally interrupted by
FACCH transmissions. This should also be tested. Lets ad a _facch
variant for the two speech test variants we already that injects a FACCH
from time to time.

The purpose of these new test cases is to demonstrate a problem
described in OS#4823: the IUT sends *dummy bursts* in absence of
MT RTP frames, so on the MS side it looks like RF failures.
It's not yet clear what needs to be sent by the BTS in this kind
of situation, but at least we can verify that whatever is sent
can be decoded on the MS side without CRC errors.

With PCUIF 10 the remote can be IPv4 or IPv6.
Add all missing parts including SNS IPv6 elements,
the support to omit IPv4 elements and a PCU_Tests_SNSv6.cfg
configuration to run all tests with IPv6

When the test is executed outside of docker, having to manage all
those different IP addresses while manually starting programs can be
quite cumbersome. Let's just run everything over localhost, like
we always do with other tests.
Now the only cumbersome command to start is trxcon, as it defaults to
only one TRX and adding additional TRX is rather complicated:
./fake_trx.py --trx TRX1@127.0.0.1:5700/1 --trx TRX2@127.0.0.1:5700/2 --trx TRX3@127.0.0.1:5700/3
