Currently we use isbound() in f_start_handler() to check if the BTS
which we want to connect is indeed populated. However. isbound()
seems never become true in this particular situation.
- Use isvalue() instead of isbound()

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
management messages, but BSC_Tests was not updated with this port,
resulting in RSL_Emulation enqueuing messages to the port which then
creates dynamic test case failures.
Let's simply connect to the port, even though we currently are not
interested in any of the messages received there (mainly
RSL_MT_BCCH_INFO during startup).

The testcase TC_paging_imsi_nochan assumes that a paging for no
channel, with no specifc cell associated and without TMSI is
illegal. This is not correct. All these fields have legal values
and the TMSI field is optional.
- Replace the testcase implementation, use f_pageing_helper() to
create the paging.

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.
We need to add handling for a socket error in IPA_Emulation because
otherwise these tests do not pass reliably as some closed connections
are not properly detected.

When f_expect_chan_rel() is called after receiving the BSSMAP
RESET and DISC.ind f_expect_chan_rel() is called. The flush
parameter is not set, which means the default flush = true is
valid. This leads into an early flush of the RSL Queue and
tosses the RSL RELEASE REQUEST we expect, so the test can not
pass, even when the BSC sends the RLEASE REQUEST.
Looking further up in the code. IPA_RSL[0].clear is called,
so the Queue is flushed to get rid of unwanted messages from
the IMMEDIATE ASSIGN. There is no need to flush the queue
a second time anyway.
- Do not flush the RSL queue, set flush=false when calling
f_expect_chan_rel()

When we page an unknown/unsupported CellIdentifier format, OsmoBSC
decides to page on all BTSs to be safe. This way we have a chance of
making communication happen, rather than breaking it.

During assignment or hand-over, a given TTCN-3 component may be
interested in registering more than one channel number. Add an explicit

we already do in GSUP, MNCC and others.

The point of this test is to verify that *no* paging messages are sent
if "No cell" is given as cell identifier list by the MSC. We can thus
not use the existing pageing_helper function, but have to handle this
a bit differently.
This makes TC_paging_imsi_nochan runs pass.

When Change-Id I10fc9f60c58c6b7ed424a86ce23bf6b9802c9eb1 was merged,
OsmoBSC started to always allocate SDCCH first, no matter what the
establishment cause. This basically means we don't do very early
assignment anymore. TC_exhaustion must be adapted to allocate all
SDCCH and all TCH before failing.

This way we benefit from the ability to handle the RR MODE MODIFY,
RSL MODE MODIFY, IPA CRCX and IPA MDCX capabilities of the MSC_ConnHdlr
component. While each test case now needs a separate function in
addition to the actual testcase, this allows for more flexibility
and a more complete emulation of BTS behaviour.

Using the MSC_ConnHdlr component, we can now handle the BSSAP (MSC)
and RSL (BTS) side of a single radio channel.
Change-Id: I00dcf1e4eaa7f133788cc01fbbcd4148a0258ef4
The existing tests were implemented directly on top of the BSSMAP
and RSL CodecPorts. If we loop in the RSL_Emulation and
BSSMAP_Emulation components, we can properly multiplex/demultiplex
multiple MS (radio channels) on both the RSL and the MSC (SCCP
connection) side.
In order to have a single component that handles both the RSL and the
BSSAP side of a given channel/subscriber/call, we introduce the concept
of BSSMAP "Expects", where the test csse can register the L3 INFO that
it sends in the RLL ESTablish INDication on the RSL side, so the BSSMAP
handler cna route the BSC-originated SCCP connection with that L3 INFO
back to the same component. This is a bit inspired "in spirit" of the
"expect" mechanism of netfilter connection tracking.
