If we're emulating BSC/BTS/MS, then we must be able to dispatch
incoming paging requests based on their IMSI or TMSI to the right
ConnHdlr component. This introduces a new table to facilitate that
dispatch.

If the ConnHdlr initiates an outbound connection, it needs to know
once that connection is established if it wants to send further
data. Transform the N-CONNECT.confirm into a MSC_CONN_PRIM_CONF_IND
and send it to the ConnHdlr.
Make use of it from the MSC_Tests when issuing a Complete L3 Info.

It's quite cumbersome if the user of the BSSMAP_Emulation (the ConnHdlr)
will have to manually decode the DTAP in every BSSAP/DTAP message he
receives (and encode on the transmit side). Let's introduce a new
optional mode in which the DTAP messages are already decoded for
more convenient matching inside the ConnHdlr.

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.
