This change introduces new version 10 specific extensions, in
particular: the frequency hopping parameters of each timeslot.
These parameters are used to compose Channel Description IE
in the packet resource assignment messages.
In order to maintain backwards compatibility with version 9 of
the PCUIF, and thus to still be able to run test cases against
the latest release of osmo-pcu, I kept the old parts of the
INFO.ind and gruoped them together with the new records
into union 'PCUIF_InfoTrxs'.
During decoding, the content of this union is resolved by the
TITAN's RAW codec itself, depending on value of the 'version'
field. During the encoding, it's the responsibility of the
API user to set a proper field of the union. I implemented
both f_PCUIF_ver_INFO_{Trxs,PDCHMask} helpers for that.
Version 9 is kept as default, so this change can be merged
independently of the actual implementation. We can bump
it and remove the compatibility glue once the new versions
of both osmo-bts and osmo-pcu are released.

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.

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.

express that in cB (centiBels).

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.

This adds the following test cases to BTS_Tests_LAPDm.ttcn:
* TC_sabm_retransmit_bts()
* TC_sabm_invalid_resp()
* TC_sabm_dm()
* TC_establish_ign_first_sabm()
* TC_iframe_seq_and_ack()
* TC_iframe_timer_recovery()

The f_init() function itself can very well derive the identity using
the built-in testcasename() function. There's no need asking users
to do that - many of them don't do it in the first place :/

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.

In BTS_Tests.ttcn we used to compose L1ctlDataReq manually. This
can be done by ts_L1CTL_DATA_REQ_SACCH() template itself, so
let's abstract BTS_Tests.ttcn from doing that.

When no PCU is connected to the BTS, the BTS should mask the GPRS
indicator from the SI3 rest octets to indicate "no GPRS support"
in the cell. This will cause phones not even trying to send us
RACH requests for GPRS ATTACH, RAU, etc.

This test will currently fail due to a MODE MODIFY NACK, even though the
channel mode is not modified.

When executing the test on our build slaves, we ran into the following:
> Number of TDMA Frames (1100) not matching (1073 .. 1093)
> Number of TDMA Frames (1096) not matching (1073 .. 1093)
So it seems the tolerance was a bit too tight. If the timer runs
for a bit more than the requested amount of seconds (e.g. due to
high system load), the number of TDMA frames is likely a bit higher
and hence we need to permit a larger tolerance.

This adds TC_pcu_socket_connect_multi, which verifies that a second
connection to the PCU Intrerface socket is denied while the first
connection is still established.

we introduced a new mode CCCH_MODE_COMBINED_CBCH to indicate that the
channel combination is a CCCH+SDCCH/4 with one SDCCH stolen for CBCH.
Let's make sure we actually use that mode in our CBCH related tests

This test opens a SDCCH and sends a RR SUSPEND message from the
simulated MS. It then expects the BTS to pick that up and forward
it to the PCU socket rather than via RSL to the BSC.

The four existing test in BTS_Tests.ttcn so far didn't have any chance
to verify if the invalid messages actually ended up on the air interface
or not. By using virtphy instead of trxcon, we can finally add that missing part.

As trxcon+fake_trx don't have GPRS (TBF) support yet, we cannot do
any PCU related tests involving the Um interface yet. Instead, let's
use virtphy to fill that gap. Using virtphy, we can actually
receive/transmit GPRS blocks on the simulated Um interface.
TC_pcu_data_req_{pdtch,ptcch} are moved to a new test suite
"BTS_Tests_virtphy.ttcn" which should symbolize that the related tests
are to be executed with osmo-bts-virtual + virtphy instead of
osmo-bts-trx + fake_trx + trxcon.
You also have to set the following module parameter to make this work:
BTS_Tests.mp_bts_trxc_port := -1
