Since change [1], the IPA emulation component allows us to handle
multiple IPA connections, thus multiple RSL connections. The idea
is to attach a TCP/IP connection identifier to each message.
On top of that, this change implements mapping between TCP/IP
connection identifiers and RSL stream identifiers, so we can
finally talk to any of connected transceivers (up to 4 for now),
not only the last connected one (as it was before). The actual
mapping is done during the IPA identification procedure.
Instead of forwarding ASP_IPA_EVENT_UP to a test case, the RSL
emulation component now sends a new event - RSLEM_EV_TRX_UP,
with transceiver number (actually, IPA stream-id) attached.

So far we only checked presence of GPRS Indicator in the Rest
Octets of System Information Type 3, but this indicator is
also included in the Rest Octets of System Information Type 4.
Let's add additional test cases to check this indicator in the
Rest Octets of both message types. In order to achieve this:
a) refactor f_si3_has_gprs_indicator(), so it can handle
System Information Type 4 and its Rest Octets too;
b) separate common part from the existing test cases into
functions and (re)use them from the new ones;
c) in f_TC_pcu_socket_noconnect(), make sure to send
BCCH INFO with System Information Type 4.

We do have GPRS Indicator in SI3 Rest Octets, but for some reason

Finally, we can get rid of hard-coded octetstrings and control
every field of the Rest Octets we're sending to the IUT.
Note that template 'ts_SI4_default' did not contain any Rest
Octets at all, thus the GPRS indicator was (and still is)
absent. This will be fixed in a follow up change.

A new module is created since its tests are aimed at running against
real HW set ups to check performance of the system under high loads.
As a result, tests in here will usually require a specific config file.

Some tests need direct access to the pcu socket, however, when working
with hardware bts this socket is not always available. The tests that
depend on the pcu socket are then skipped by the testsuite.
The following tests are not automatically excluded, but require direct
PCU access. Lets exclude them as well:

Since there can be multiple PDCH channels configured on different
timeslots, different TRXes, and BTSes, the PTCCH/U handling code
in OsmoPCU needs to know the exact origin of a given RACH.ind.
Otherwise, it is not known which subscriber originated a given
PTCCH/U indication, and hence it is impossible to send PTCCH/D
Timing Advance notification properly.
Fortunately, we can extend the RACH.ind message without even
bumping the protocol version, because every single PDU has a
fixed size defined by the largest message - INFO.ind. In case
if the actual message payload is smaller, the rest is filled
with a constant padding byte (0x00).
Older versions of OsmoPCU will consider the new fields as padding,
while the messages from older OsmoBTS versions will always have
both fields set to 0x00. Since C0/TS0 cannot be configured to
PDCH, this can be easily detected on the other end.

We have a module parameter 'mp_l1_supports_gprs' that indicates
whether the L1 back-end (trxcon, virt_phy, or Calypso) does
support PDCH and TBF management.
The TC_pcu_ptcch does not require support of TBF management, only
PDCH (namely PTCCH) needs to be supported. This is already
implemented in trxcon, and can be easily implemented for Calypso.

This test case is aimed to verify handling of both PTCCH/U and
PTCCH/D logical channels, recently implemented in [1]. This is
done by sending 16 Access Bursts on PTCCH/U, and then by
sending a random data block on PTCCH/D.
The existing TC_pcu_data_req_ptcch does not cover PTCCH/U, and
moreover involves TBF handling which has nothing to do with
PTCCH. Let's keep it anyway.

Test BTS_Tests.TC_dyn_osmo_pdch_act_deact was sporadically failing due
to receiving IND_INFO on the PCU port with pdch_mask related TS bit set
to 0 after sending a PDCH ACT. That happened due to a race condition
because PCU send IND_INFO periodically. As a result, it can happen that
BTS sends an IND_INFO after PCU.clear was called and before the PDCH ACT
is handled.
Commit 446e07bc77 already did same fix for
f_dyn_ipa_pdch_(de)act() family, but didn't change this one.

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).

The testcase failed becaues of an unexpected RSL Error Indication from
the LAPDm system which was in the RSL emulation queue when tearing down

By calling f_rsl_chan_deact() the queue gets flushed until the RSL

Before this patch, sending special TRXC commands to FakeTRX, such as
FAKE_TOA and FAKE_RSSI, from ConnHdlr resulted in a receive timeout
waiting for the response.
As it turned out, both the test_CT and the ConnHdlr have a TRXC port,
as depending on the test one would want to globally control it
from test_CT or from within a ConnHdlr.
However, only one of the two should be active (connected) at any given
point in time. Otherwise we'll have two UDP sockets on the same bind
port, and it's more or less random on which of them it ends up.
Let's add an optional parameter 'trxc_comp', which would indicate
whether we need to control TRXC from ConnHdlr or not.
Let's get rid of both f_trxc_connect() and f_main_trxc_connect(),
which basically do the same, but run on different components.

The idea of this test case (as can bee seen from its name) is to
verify handover RACH detection. What we basically do is:
1. Activate a logical channel on the BTS side (HO_SYNC for now);
2. Switch the MS (e.g. trxcon) to that channel without waiting
for Immediate Assignment and sending Access Burst;
3. Send an Access Burst on that channel using RA = HO_REF;
4. Wait for RSL HANDOver DETected from the BTS;
5. Release a dedicated connection.
There is no way to verify if the Handover Reference received
from the MS matches the one that was sent to the BTS. We can
introduce a separate test case that would just send an Access
Burst with RA != HO_REF.
