OsmoBSC has some misunderstanding about how IPA CCM works and hence
we need to work around this until that bug is fixed in OsmoBSC.

By default all the elements in the conn table seem to be considered
<unbound>.
f_cid_create() manages to set ra, ra_fn and comp_ref in the
ConnectionData element, but checking for
ispresent(ConnectionTable[i].ra) still returns false while
log(ConnectionTable[i].ra) returns 23. Setting every optional element to
omit as f_cid_clear() does before using the connection table seems to
solve this issue.
The assignment_fr_* tests now continue after receiving the Immediate
Assignment, but still fail after receiving the CM Service Request.

Let's verify the operation of the CIPHERING MODE COMMAND as issued
by MSC, performed by BSC and implemented by simulated BTS/MS.

They all are related to a dedicated channel and carry a channel number
as first information element.

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.

This allows us to verify if the BSC pages *only* where it is supposed
to page based on the cell identity list in the 08.08 PAGING.

So far, only the IPA client was instructing the IPL4asp to use
the message-desegmentation function. The server didn't use it, leading
to inconsistent behaviour.
