BSC_Tests: Prepare for tests based on {RSL,BSSMAP}_Emulation
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.
