We create a new Osmocom_CTRL_Adapter module which can be used by
test suites using the 'extends' functionality.

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.
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.
