In this test case, the MSC performs a hard SCCP release of the

but we simulate a broken/lost MS which doesn't respond to that.

This test establishes an SDCCH for each iteration. However,
* due to OS#3333, osmo-bsc is currently not properly releasing those
lchan's,
* due to OS#3222, we furthermore don't allocate "larger" channels like TCH
and as a result on a combined CCCH system we only have 4 SDCCH, which
is less than the 8 that we try to use here.

The helper function f_establish_fully() checks the channel type
for compatibility. If the channel type is compatible with the
desired mode a channel mode modification could be necessary if
the current channel mode is different from the desired channel
mode. However, this is not checked at the momemend. We just
blindly expect a MODE MODIFY message from the BSC and ignore
the cases where the current channel mode and the desired channel
mode already matches up. This is the case if only a signalling
channel is requested with f_establish_fully for example.
- Check if the channel mode of the current channel and the
desired channel mode match up.
- Make sure that the MODE MODIFY from the BSC is only
expected when the channel modes are different.

A51 the values match up by coincidence, from A5/2 onwards they differ.
- Add a function to convert the BSSMAP representation to the RSL
representation and use the converted value to set up the temlate
for the expected RSL message

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.

We shouldn't "pass" f_establish_fully() in the assignment case

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.

It's quite cumbersome if the user of the BSSMAP_Emulation (the ConnHdlr)
will have to manually decode the DTAP in every BSSAP/DTAP message he
receives (and encode on the transmit side). Let's introduce a new
optional mode in which the DTAP messages are already decoded for
more convenient matching inside the ConnHdlr.

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.

So far, BSSMAP_Emulation used the SCCPasp_SP_PORT directly, explicitly
calling BSSAP encode/decode functions while processing the primitives.
Let's clean this up and use the BSSAP_CodecPort which has meanwhile
been developed as a dual-faced port that can be stacked between SCCPasp
and the user to avoid any manual encode/decode function calls.

We used to rely on out-of-tree git clones to be prepared by the user.
This commit changes the system to make sure we clone all git repos
we depend upon into the 'deps' folder, and then setup the symlinks
to that folder. As a result, we should be able to support
self-contained builds using the makefiles in this repo.
We use the "oml-connection-status == degraded" to determine if
the OML connection has been brought up by the external helper.
However, this status is advertised from the moment the ID_ACK was
issued on the OML connection, and *not* only from the moment on
when we're expecting the RSL connection (after initializing all MO).
Let's introduce some delay to avoid running into a race condition here.
The proper solution is to implement OML inside the test suite, which
is too large of a task to be done right now, where the focus is on
RSL+BSSAP testing.
Rather than using the more complex RSL Emulation and BSSAP emulation
components, we attach to the RSL and BSSAP Codec Ports and send some
messages back and forth for low-level testing such as timeouts, response
to RACH requests, failure of MSC to react to CR requests, etc.
