OsmoBSC does some minimal parsing of l3 content to select MSC target,
match paging response to paging request, etc.
Since tests right now use potentially invalid data, osmo-bsc is not
rejecting conns providing invalid l3 content.
This commit makes sure TTCN3 tests pass valid l3 payloads to osmo-bsc,
so that they keep working once osmo-bsc starts rejecting invalid IEs it
parses.

New TC_assignment_osmux_bts is added which tests Osmux used only
BTS<->BSC.
Existing TC_assignment_osmux is renamed to TC_assignment_osmux_cn,
and a new TC_assignment_osmux is added which tests using Osmux on both
sides (towards BTS and CN).

That config is used to control the use of osmux between BSC<->MSC. Since
we'll add support for Osmux in BTS<->BSC, we want to test that in a
separate way. Let's rename it so that we can add a "use_osmux_bts" later
on.

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.

Properly clean up conns in the end. Use COORD and new COORD2 ports to
daisy-chain coordination between the four components.

Properly clean up conns. To know when the multiplex is ready, use the
COORD port to tell the other component.

Keeping the logical channel active may affect test cases executed
after TC_chan_act_to_vamos. Clean up after the test to avoid that.

This way functions like f_inet_addr() and f_inet6_addr() can be
used directly without converting between bytes and integers.

In BSC_Tests_VAMOS.ttcn, in f_est_and_reassign_to_secondary_lchan()
there is a missing channel release ack. By allowing ASP_RSL_UD, this rel
ack can be sent trivially.

BSC_Tests_VAMOS.ttcn is separate from BSC_Tests.ttcn in order to
instruct osmo-bts-omldummy to pass BTS_FEAT_VAMOS == true in the OML BTS
attributes.
Add tests:
TC_chan_act_to_vamos()
TC_mode_modify_to_vamos_fr()
TC_mode_modify_to_vamos_hr()
TC_assign_to_secondary_lchan_fr()
TC_assign_to_secondary_lchan_hr()
TC_vamos_multiplex_tch_f_tch_f()
TC_vamos_multiplex_tch_h_tch_h_tch_h_tch_h()
