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.
