This way it's consistent with ts_RSL_ChanMode, and there is
no need to pass dtx_downlink := false as the first param.

The testcase TC_meas_res_sign_tchX activates a traffic channel in
signalling mode and checks the RSL resulting measurement reports.
The CHANnel ACTIVation message sets "SDCCH" as "Channel rate and Type"
value. This is invalid, the "Channel Rate and Type" sould be set to "Half /
Full rate TCH Channel Lm / Bm" (while the speech or data indicator is
still set to "Signalling")

This test case is very similar to TC_ms_pwr_ctrl_constant(), but the
key difference that we simulate sharp UL RSSI changes between -50 dBm
and -100 dBm on each iteration.
The 'uplink-power-target' (-75 dBm) is right in the middle of the
change range, so with EWMA filtering and 80% smoothing it's expected
that all averaged UL RSSI values would be around -75 dBm.
It's expected that the Uplink power level remains constant, however
this test case fails at the moment. The problem is that the IUT is
still quite sensitive to small deviations from 'uplink-power-target',
so ideally we should introduce a 'hysteresis' defining a range:
['target' - 'hysteresis' ... 'target' + 'hysteresis']
in which the MS power loop should not trigger any power changes.
For example, let's say:
'uplink-power-target' is -75 dBm (default), and
'hysteresis' is 8 dBm,
so then the range would be: -83 dBm ... -67 dBm.

When several TRX are set up, it can be that in between a RSLEM_EV_TRX_UP

When our emulated PCU sends a DEACT.req to the BTS, there is no way
of knowing when exactly that command will have been completed: There is
no confirmation sent in response.
Let's introduce a f_sleep(1.0) to give the BTS sufficient time for
deactivating the channel.
This will make TC_pcu_deact_req pass reliably. It currently fails
in about one third of all test executions on jenkins.

f_init / f_init_pcu simply save the first PCU_INFO_IND
in g_pcu_last_info. That first one might still be wrong as
the PCU might connect to the BTS before the BTS is configured

Let's wait for 2 seconds and actually use the last (most recent)

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.

Some types of System Information (mostly the Rest Octets) are not
fully implemented, so calling the generic dec_SystemInformation()
may result in a DTE. Let's add dec_SystemInformationSafeBT() with
"prototype(backtrack)", so it would return a non-zero integer if
decoding fails. Let's add a wrapper dec_SystemInformationSafe()
that would additionally check the RR Protocol Discriminator.

The testcase tests if a CHANNEL REQUEST on the RACH leads to the correct
CHANNEL REQUIRED message on RSL level. When a MS is sending a CHANNEL
REQUEST to establish an emergency call, it uses a slightly different
layout for the request reference (RA). Lets add another similar testcase
(TC_rach_content_emerg) to cover the emergency call situation as well.

This test verifies power ramping (up) is working fine during BTS
startup.
config files are updated to make sense:
* "nominal power" in osmo-bsc.cfg reflects correct default nominal tx
power of fake_trx.
* "osmotrx tx-attenuation" in osmo-bts.cfg is removed to let osmo-bts
use the value received through OML (max_power_red 20).
* "power-ramp step-size" in osmo-bts.cfg is increased to speed up the
test. There's no good reason to keep it lower.
