The current paging load tests only test what happens when the paging
load is introduced from the PS side. However there are no tests that
tests what happens when PS pagings are introduced from the PCU side
into an already overloaded system.
osmo-bts was equipped recently with a mechanism that detects congestive
situations. Once a congestion is detcted osmo-bts will drop pagings from
the BTS side. The rationale of the new testcase is that the behavior
must not change when the PS pagings start since osmo-bts is dropping
them.

Since recently, we do have NOPE indications in the virtual Um
environment. Somehow this broke test cases for the MS power
control. Releasing the channel makes everything work again.

Recent changes [1] to osmo-bts make it periodically send the
RF RESource INDication messages for each transceiver over the
A-bis/RSL. These messages block the queue of 'RSL_CCHAN' port
and make the paging related test cases fail. Ignore them.

Unfortunately, trxcon does not support handling more than one
connection in parallel. If there is already one connection
established, it would reject all other connection attempts.
This causes an error in f_handler_init(). As a quick hack,
let's allow running BTS_Tests.ConnHdlr components without
establishing L1CTL connections at all.

The expectations of this test case were wrong. The IUT would first
accept() an additional connection and then close() it immediately.
Since there may be other messages, like TIME.ind and DATA.ind, the
'alt' statement would not match successful connection result, and
instead would unblock the flow due to timeout.
The titan.TestPorts.UNIX_DOMAIN_SOCKETasp had to be changed [1] to
send UD_connect_result with ERROR if recv() returns zero or a negative.

The PCUIF connection involves a lot of frequent messages, such as
the TIME.ind and since recently DATA.ind with len=0. As a result,
the test suite logs are getting unreadable due to lots of coding
warnings and port queueing notifications.
This change is aimed to improve the situation a bit, by establishing
the PCUIF connection only for those test cases which actually use it.
Side effects:
* TC_pcu_socket_verify_info_ind becomes reliable, because the
PCUIF establishment is done after the RSL bootstrapping;
* TC_pcu_socket_connect_multi starts to fail, because it used
to pass due to timeout, since not all messages are handled
in the 'alt' statement.

Whenever the BSC is updating SI1, SI3 or SI13 via RSL, the PCU should be
informed about the change via PCUIF as well. For SI13 this is already
the case and a testcase exists. The PCUIF protocol is
now capable to update SI1 and SI3 as well.
- Update BTS_Tests.TC_pcu_ver_si13 so that it works with the current
protocol version
- Add BTS_Tests.TC_pcu_ver_si3 and BTS_Tests.TC_pcu_ver_si1 that test
SI1 and SI3 as well.

In some cases GsmArfcn itself is not enough. It case of L1CTL
and GSMTAP, it needs to be equipped with a band discriminator:
- DCS / PCS (as the numbers may overlap),
- Downlink / Uplink (not yet there).
Let's rename this record and move it to GSM_Types. Also, add
send / receive tamplates, so we can add new fields later.

It will be easier to use this list / array in non-L1CTL specific

The new altstep reduces code duplication and simplifies access
to the L1 SACCH Header. It uses dec_SacchL1Header() to decode
the header, and would apply the received TA / MS Power level
values by default (see 'do_apply' parameter).

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.

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.

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.
