Unlike the RSL_IE_MS_Power, where power_level is 5 bit long, in
the RSL_IE_BS_Power it's 4 bit long. Fix this.

On channel establishment the first measurement result may lack the
measurement reports from the MS. This is normal behavior, so lets
tolerate that.

In this testsuite, we simulate BTS and CBC by attaching to RSL and CBSP
protocol interfaces of the BSC. We then issue a variety of CBSP
commands to the BSC and check for corresponding action on both the BTS-
facing RSL as well as responses on the CBSP side.

osmo-bts does currently not use the signaled lchan BS power level, nor
does it update the BS power IE returned in the measurement results.

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.

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

The existing code structure could only test for normal messages with a
NULL default, but didn't handle situations where normal and/or schedule
messages were superimposed on top of DEFAULT messages.
Also, prepare the infrastructure for testing both CBCH BASIC and CBCH
EXTENDED.
No new tests are introduced, the code should behave identical before
and after this patch.

According to 3GPP Ts 48.058, every logical channel can receive some
specific SACCH filling at the time of RSL channel activation. This
overrides the global SACCH FILLING.

Usually the MS power is controlled by the BTS and there is no continous
supervison by the BSC needed. However, a scheme where the BSC takes care
of the power control loop exists. The power is then set via RSL using an
RSL MS POWER CONTROL message.
This tests establishes a dchan and then sends MS POWER CONTROL messages
with differen power levels and then checks the presence of the power
level set in the MS POWER LEVEL field of the SACCH L1 header.

This is quite useful when one needs to expect an RSL UNITDATA
message with any payload. Let's set 'l3_info' to '?' by default,
like it's already done for 'ts_RSL_DATA_*'.

The 'tr_RSL_UNITDATA_IND' is a 'response' template, so there
is no reason to restrict 'link_id' to any obvious value.

Add tests TC_tch_sign_l2_fill_frame and TC_tch_sign_l2_fill_frame_dtxd.
TC_tch_sign_l2_fill_frame is already passing and verifies that fill
frames are sent if there is nothing else to transmit on a SDCCH4/SDCCH8,
TCH/H, or TCH/F signalling channel where DTX is disabled for downlink.
TC_tch_sign_l2_fill_frame_dtxd is currently failing. It verifies that
only specific fill frames are sent, as required by GSM 05.08 for TCHF
signalling channels with DTX enabled for downlink. At present, our
implementation generates no fill frames in this case, which is one
piece of the problem described in issue OS#1950.

Until now, the test went from RR Handover Command directly to RR Handover
Complete, and osmo-bsc didn't mind it. However, the normal handover procedure
requires an RSL Handover Detect to be sent in-between those. Send that.

The existing test simply sent 1000 messages via RSL without checking
what actually arrived on the radio interface, or without
expecting/counting any RSL DELETE IND.
Let's fix this by introducing test sending IMM.ASS at three different
rates, with related expectations in terms of nubmer of IMM.ASS arriving
on Um vs. RSL DELETE IND arriving at BSC.

The MDISC_IPACCESS is only used for the media (CRCX/MDCX/DLCX) related
commands, not for the PDCH activation/deactivation. The latter uses
normal MDISC_DCHAN.
Also, add the inverse templates for PDCH actiation/deactivation, so we
now have both receive and transmit template for each of the 6 related
messages (activation, deactivation, plus each their ACK + NACK).

The way how TTCN-3 templates work we cannot use a template parameter

RTP_PT2, or (alternatively) on any messages whether or not they have
a RTP_PT2 IE at all :(

We're testing at 80% and 200% of PCH capacity, both for either IMSI-only
or TMSI-only paging requests. The way how we test ensures:
* the expected number of paged mobile identities end up on the Um interface
* we implicitly check the queuing limit of 200 paging records by
overflowing it in the 20-seconds-of-200%-load cases
* we implicitly check the batching of mobile identities into different
paging types
* we test the PCH load reporting over RSL
As a side note, in case you were ever wondering what's the expected
paging throughput / capacity, there are now helper functions to compute
it. For our combined CCCH/SDCCH4, it's about 16 IMSIs per second or
about 32 TMSIs per second.

This is a template that goes beyond the 3GPP specs, as it expects
presence of certain optional IEs which we know are always present
in the OsmoBTS case.

So far, the RSL templates have been used for BSC testing, i.e.
TTCN3 behaving like a BTS. Now we want to test the BTS, so we
have to "invert" the receive/send direction and hence also need
the inverse templates.
This doesn't add *all* of them, but a sufficiently large number for our
first testcases against OsmoBTS.
