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.

Recently, encryption testing was added to the inter-MSC HO test. Instead
of sending the chosenEncryptionAlgorithm from the receive-template side
forward the actual received one (rx "*" usually means tx is "omit").

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().

Move the ciphering calculations from f_mm_common() to new function
f_get_expected_encryption(), so that it can be re-used for ciphering in
inter-BSC handover (upcoming patch).
Add tr_BSSMAP_CipherModeCmd2() to conveniently use the values returned
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.

All msc tests involving classmarks suffer from the same problem: if a
existing subscriber is reused the old classmarks will stick, since the
msc only overwrites updated parts of the cm when receiving a new cm, so
"downgrading" the existing classmark information is not possible.
This is circumvented here here by using different imsi suffixes,
the last param passed to f_start_handler.
Additionally the handler will now properly respond to cm requests
by the msc, i.e. in case the early cm is not sufficient for a5/4
because it lacks cm3, so the msc attempts once to query the cm,
hoping to get a cm3.

We already have TC_cmserv_imsi_unknown, but lack a test that shows CM Service

Looking at OS#4721 I vaguely expected an ID Request to also happen during CM

the MS to perform a proper LU subsequently.

I194271af2acb37b4f8cc2d106ab2fd2b0d443589, osmo-msc properly records these for
successful Complete Layer 3 procedures.
Incorporate verification of the LAC and CI in all tests calling f_perform_lu()
and f_expect_clear(). Implement by scraping the output of vty
'show subscriber imsi 1234 conn'
Some tests model a failure to attach, or expire the VLR record: for those, add
parameter verify_cell_id to g_pars, and pass it as false, to skip checking the
LAC and CI.
Disable CI checking for all Iu tests globally in f_verify_vty_lac_ci(), see
OS#4634.
For the latest build, which does not yet record LAC and CI properly, provide
mp_enable_cell_id_test, which skips all cell id verification if set to false.
