Let's only create BSC handlers (no MM handlers) in tests validating CBSP
specific features.
A new test is added to specifically validate scenarios with both an MME
and BSC attached to the CBC.

A comment in f_TC_rsl_ms_pwr_dyn_up() states:
> By default, the MS power loop gets triggered every 4th SACCH block (1.92s).
> We need 9 * 4 dB steps to get from 0 dBm to 33 dBm, so 9 * 1.92s total.
> Add an extra offset to avoid race conditions: +1.92s.
so the alt statement is expected to block for 19.2s, while the guard
timer is set to 20.0s by default. This is not enough, given that
f_TC_rsl_ms_pwr_dyn_up() also needs to wait for the first SACCH block
before entering the alt statement.
Let's give it more time to run in order to avoid sporadic failures.

Sending L1CTL_DM_REL_REQ does not make the L1 tune back to CCCH/BCCH.
We need to send a L1CTL_FBSB_REQ after releasing a dedicated channel
if we want to establish another one. This is essential when running
tests using Calypso PHY, and will be required once we have proper
trxcon_fsm implementation [1] merged.

Recently I noticed sporadic CBSP test case failures on Jenkins:
Timeout waiting for RSL_OSMO_ETWS_CMD (disable)
BSC_Tests_CBSP.ttcn:1209 BSC_Tests_CBSP control part
BSC_Tests_CBSP.ttcn:1056 TC_cbsp_emerg_write_bts_cgi_cchan_disable
The related timeout is set to 5.0 seconds in f_exp_rsl_etws(), what
matches the Warning Period IE sent in CBSP WRITE-REPLACE message.
Adding a debug log printing T.read on receipt of RSL_OSMO_ETWS_CMD
reveals that we're cutting it too close: the message arrives just
a few milliseconds before the timeout expires.
f_exp_rsl_etws(): T := 4.999196s, remaining 0.000804s
f_exp_rsl_etws(): T := 4.998683s, remaining 0.001317s
f_exp_rsl_etws(): T := 4.999344s, remaining 0.000656s
Let's increase the timeout value (+0.5s) to avoid sporadic failures.

The TC_imm_ass_pre_chan_ack_dyn_ts sporadically fails on Jenkins.
Similar to [1], this is happening because the VTY command setting
the 'immediate-assignment' strategy back to 'post-chan-ack' is
being sent/processed earlier than the CHANnel REQ message.
TC_imm_ass_pre_ts_ack_dyn_ts is likely affected too, also fix it.

This way we trigger more code paths in the GGSN_Tests IUT, like parsing
the QoS IE. This is interesting because the QoS IE has quite a complex
encoding, specially the MBR/GBR part. Those fields in turn are also

So far it was possible to communicate with multiple BTS instances,
however we were limited to only one IPA/RSL connection per BTS.
Communicating with additional TRX instances requires establishing
additional per-TRX IPA/RSL connections. This patch extends the
testsuite infrastructure, so that it becomes possible to have
up to 4 individual TRX instances for each BTS.
* Introduce record 'BtsParams', store per-BTS params in an array.
* IPA_RSL_PT: test_CT.IPA_RSL[NUM_BTS] -> test_CT.IPA_RSL[NUM_BTS][NUM_TRX].
* BTS_State: test_CT.bts[NUM_BTS] -> test_CT.bts[NUM_BTS][NUM_TRX].
* f_init_bts_and_check_sysinfo() accepts number of TRX instances.
* f_init_bts() accepts number of TRX instances to configure.
* f_ipa_rsl_start() accepts a BtsTrxIdx param.
* Introduce record BtsTrxIdx allowing to specify BTS/TRX index values.
* f_ipa_tx(), f_exp_ipa_rx() accept a BtsTrxIdx param (default {0, 0}).
* f_est_dchan[_dyn]() accept a BtsTrxIdx param (default {0, 0}).
** and store the given BtsTrxIdx in returned DchanTuple.
* f_chreq_act_ack() accepts a BtsTrxIdx param (default {0, 0}).
* f_expect_chan_rel() accepts a BtsTrxIdx param (default {0, 0}).
* f_exp_ipa_rx_nonfatal() accepts BtsTrxIdx (default {0, 0}).
* f_exp_chan_rel_and_clear() uses BtsTrxIdx indicated in the given DchanTuple.
* Fix CTRL/statsd expectations in TC_stat_num_bts_connected_[123].
* Fix CTRL expectations in TC_ctrl_trx_rf_locked.
The major limitation is that MSC_ConnHdlr components still have no
access to additional TRX instances - this can be implemented later.
