This is an early WIP, we actually will need to establish two calls/legs

In case we want to derive other component types by extending
MSC_ConnectionHandler, we will want to connect additional ports
before starting the component.
Hence, split the connect part into f_create_handler(), while keeping
the create + start part in f_start_handler().

The helper function f_tc_ciph_mode_a5(), thich performs all of the
three tests currently disables the ASSIGNMENT COMMAND since due to
a bug in OsmoBSC a MODE MODIFY would be attempted by the BSC,
causing the testcase to fail.
The problem in OsmoBSC is now fixed and the ASSIGNMENT COMMAND can
be re-enabled again for this test. However, the test function
includes and expects an AoIP transport layer address, which is
not included for signalling assignments.
- Make sure no AoIP transport identifier is included in ths
ASSIGNMENT COMMAND
- Do not expect an AoIP transport identifier in the
ASSIGNMENT COMPLETE from the BSC
- Re-Enable the generation of the ASSIGNMENT COMMAND

In non-handler mode, the SCCP emulation is currently started before
there's a user registered to SCCP_SP_PORT. If the first BSSMAP
package arrives from the network, then the SCCP_Emulation will crash
as it cannot deliver the resulting SCCP user primitive to the user.
Let's split start from initialization, so user code can still register
something to SCCP_SP_PORT before starting SCCP_Emulation.

The cell identifier used by the paging tests is 001-01, i.e. uses a
2-digit MNC. With the introduction of 3-digit MNC support in osmo-bsc,
the paging tests became incompatible with a osmo-bsc config with:
network country code 1
mobile network code 1
Explicitly declare a Cell_Identity with 2-digit MNC (includes an 'f').
Also, fix f_enc_mcc_mnc to properly encode 2-digit MNC values.

Instead, osmo-bsc patch I0f8c9c4e6b6850b15c70250fd3f88bdf75f9accf decides to
signal full BSSMAP Clear Request to the MSC first, so expect that first.

A test with BSSMAP Clear involved would also be a nice addition, but this so
far tests a direct RLSD from the MSC.
(One way to invoke a typical release situation would be a scenario like in
TC_chan_rel_rll_rel_ind(), but that test currently fails; another would be to
directly invoke a BSSMAP Clear from the MSC first.)

When the test component ends and the underlaying
components are shut down. Messages from the system
under test may still be picked up and forwared. When
a message is handed from one component to one that
is already shut down, the testcase is flagged as
errornous setverdict(error).
An idea to fix thisis to stop all test ports using
all port.stop. However, this does not solve the
problem entirely. We still observing errors.
- add f_shutdown_helper() and call it from the
end of each testcase
- perform an all port.stop; in f_shutdown_helper()
to freeze all communications between the ports
of the different components.

The testcase TC_paging_imsi_a_reset sends a paging request that
causes pagings on all cells. Then it performs a BSSMAP reset and
checks if the paging has stopped. In order to be sure that paging
requests from before the reset procedure are not mistakenly
detected as after-reset-pagings the RSL queue is cleared. However
this is only done for IPA_RSL[0], which means IPA_RSL[1] and
IPA_RSL[2] still contain old paging requests, which lets the test
fail.
- Clear IPA_RSL[1] and IPA_RSL[2] as well.

RSL_Emulation has recently gained a port for the common channel

resulting in RSL_Emulation enqueuing messages to the port which then

This adds two new tests: One for RSL, and a second one which performs
the same test on the OML port. Both tests open an IPA connection and
send a unit ID which is unknown to the BSC. The tests expect the BSC
to close the connection immediately.

otherwise these tests do not pass reliably as some closed connections
are not properly detected.
