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.

Let's use the preprocessor to avoid IPA_Emulation pulling *all*
dependencies into each and any of our projects. The code readability
suffers a bit from the many #ifdefs, but compilation speed increases
if we don't have to pull in all those (recursive) dependencies.
After all, a BTS test case will never need SCCP, GSUP or MGCP.

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()

The point of this test is to verify that *no* paging messages are sent

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.

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.
