It can happen that the RLCMAC req arrives at osmo-pcu before the
CS_PAGING we send to it over BSSGP, in which case osmo-pcu will schedule
an RLCMAC DL Dummy Block. Take into account this scenario to avoid
failing id it occurs.

Since recently osmo-pcu arms the X2002 in a more fitting place (later,
when paging.cnf is received from osmo-bts over PCUIF).
Since we use same X2002 value in TTCN3 to wait for the timer to trigger,
in the past it was always fine (the X2002 at osmo-pcu always already had
triggered before the one in ttcn3 after receiving the ImmAss).
However, now the timer is roughly set at the same time in both places (ttcn3 and
osmo-pcu) and hence there may be race conditions where we request a
DL data block before the X2002 triggered at osmo-pcu, in which case we
receive a DL dummy block because the TBF is not yet in the FLOW state

The test was expecting to always receive at least 1 DL packet with
USF_UNUSED, but since we implemented idle blocks in PCUIF that may not
always be the case anymore. If the TBF is freed in between last
requested block and next one, there may be no TBF and hence no MS
listening on the TS, so PCU will optimize and send an idle block.

I cannot reproduce the issue in my local system with docker, probabluy
due to different performance from jenkins builder. It triggers almost
every time in jenkins nightly TTCN3 PCU_tests though.
A similar fix was already introduced recently for TC_n3105_max_t3195
since PCU started submitting empty (idle) blocks when there's no TBF
listening on that PDCH. We need to update the test to account for that,
since our TTCN3 timers are not necessarily exactly matching the one at
the PCU side.

New versions of osmo-pcu support Neighbor Address Resolution over this
interface, and deprecated the old CTRL interface.
Let's use it by default while still keeping support for the old one for
a while to avoid breakage of existing deployments.
Tests run to validate:
* Old osmo-pcu still passes tests using CTRL interface
* New osmo-pcu (with new iface support) still passes tests using CTRL
interface
* New osmo-pcu (with new iface support) passes tests using new iface

This test was added a long time ago to test what used to be the previous
early implementation of T3169, which didn't follow specs as per TS
44.060.
Since recently, osmo-pcu supports tracking UL PDCH blocks and hence
properly implementing N3101 and N3101, finally also implementing T3169
correctly.
The counters N3101/3 and timer T3169 are already being tested in
following tests:
TC_n3101_max_t3169
TC_n3103_max_t3169
Since osmo-pcu I2cec531e2633281b88f69ba065c0105580c81076, time-based
T3169 is dropped and TC_t3169 doesn't pass anymore, since it had wrong
expectancies (because it's not sending RTS to osmo-pcu, hence not
triggering USF/RRBP N3101/3 timeouts).

New versions of osmo-pcu will validate the Pkt Resource Request is sent

The previously request Dummy block was processed later in an unrelated
place of the test, hence making expectations fail.
The condition T_3195.running doesn't really change the logic/behavior,
but removes an annoying warning in log files everytime the alt step is
run.

still fine.
