It sometimes happens that the ttcn3 test checks the BVC FSM state before
the gbproxy had time to process the BVC_RESET_ACK from the "SGSN". It
then reports the state WAIT_RESET_ACK which will fail the test.
Introduce a small wait to give the gbproxy some more time.

So far we were often just expecting the message type. Instead expect a
release on the proper channel number.
While hunting a test error, this confused me for a while, because a
missing handler resulted in the release message handled in the wrong
place, even though the chan_nr mismatched.

To be able to run tests on a cell other than bts 0, there needs to be a
way to select the RSL_DCHAN_PT and RSLEM_PROC_PT in various places.
Upcoming BSC_Tests.TC_cm_reestablishment depends on this, to be able to
run through an Assignment on bts 1.

Add explicit RSL_DCHAN_PT and RSLEM_PROC_PT args to functions and

establishing and assigning a channel on cells other than bts 0.
This is required for upcoming BSC_Tests.TC_cm_reestablishment().

The function f_expect_dlcx_conns() is clearly related to MGCP, and
semantically should not interfere with BSSAP by also receiving the Clear
Complete.
For some tests, this incidentally makes sense, but an upcoming test
failed in a non-obvious way because of this.

After the RSL RF Release has happened, by definition the RSL_Emulation
should no longer direct RSL messages on that chan_nr to the test
component that used to own the chan_nr in the ConnectionTable.
Before this patch, re-using e.g. an already freed SDCCH would result in
non-obvious test failure. This is most relevant for generic functions
called from various tests, but fixing all occurences anyway.

Create the routing key dynamically, before trying to unregister it. The
previous version tried to unregister a statically configured routing
key, as in TC_rkm_unreg_never_registered, but expected success instead
of the proper ERR_NOT_REG.
So after fixing osmo-stp to make TC_rkm_unreg_never_registered pass,
this test failed.

Do not assume that osmo-bsc.cfg contains "0 1 3 4" for master and "0 1 3"
for latest anymore. An upcoming test will need to change the value as
the test runs and needs a defined value to reset to.

Fixes inter-MSC handover tests: in the inter-MSC 'Handover Required', do
not send a LAI cell identifier, but a CGI one.
This is analogous to the fix applied to inter-BSC HO in
I48276acf923626db171683dfa03ef43614a71380.
Rationale:
As explained in OS#5188, 3GPP TS 48.008 allows a LAI identification only
in the Cell Identifier List IE, but not in the single Cell Identifier
IE.
In the inter-MSC HO test's Handover Required message, we so far send a
LAI identifier in a List IE to osmo-msc. And so far, osmo-msc simply
echos that in the Handover Request message's single Cell Id IE.
The LAI is, as actually defined in the spec, omitted from the single IE
in deps/titan.ProtocolModules.BSSMAP/src/BSSAP_Types.ttcn, and when
osmo-msc sends the non-standard LAI Id, ttcn3 fails to parse the BSSMAP
Handover Request message: the Cell Identifier IE gets wrong values, and
all remaining IEs are parsed as 'omit' even though they are present on
the wire. So as long as osmo-msc sends back a LAI Id, we cannot sanely
verify the Handover Request received from the MSC.
The CGI identifier type is supported in both IEs. So when the test sends
a CGI identifier in the Handover Required, osmo-msc will also reflect a
CGI identifier in the Handover Request, and ttcn3 parsing works.

Next to AuthVector vec, add boolean vec_keep. When set to true,
as_GSUP_SAI() skips the vector regeneration.
An upcoming patch adds encryption to inter-BSC handover, which will use
vec_keep := true. (See I57e43c60d4389bd301d0195179321a34401bd1dc )
Rationale:
Usually, a random auth vector is generated during as_GSUP_SAI(). For
inter-BSC handover, there are two separate virt-BSC components running.
But to be able to verify that the correct key is passed on from the old
to the new BSS, both titan components need to have the same AuthVector
data. The easiest solution is to generate the AuthVector before
launching the components, and then prevent that it is changed by
as_GSUP_SAI().

by f_get_expected_encryption().
To verify the Ciphering Mode Command in f_mm_common(), use the new
tr_BSSMAP_CipherModeCmd2(), and rely on template matching instead of
checking each IE individually.

The current paging load tests only test what happens when the paging
load is introduced from the PS side. However there are no tests that
tests what happens when PS pagings are introduced from the PCU side
into an already overloaded system.
osmo-bts was equipped recently with a mechanism that detects congestive
situations. Once a congestion is detcted osmo-bts will drop pagings from
the BTS side. The rationale of the new testcase is that the behavior
must not change when the PS pagings start since osmo-bts is dropping
them.
