Implement a proper subscriber connection mapping. Create a new
subscr_conn when one of the stored BSCs sends a conn.ind and use that
subscr_conn for all related connection-oriented messages with the same
RAN-side conn_id to send messages back and forth between BSC and MSC.
Add subscr_conn_get_next_id based on OsmoBSC's
bsc_sccp_inst_next_conn_id.
With this patch, it's possible to do a successful Location Updating
procedure between MS2 and MSC in the following network:
MS1 --- BTS1 --- BSC1 --.
BSCNAT --- MSC
MS2 --- BTS2 --- BSC2 --'

Add an initial implementation of sccp_sap_up, that assumes one BSC and
one MSC, and successfully forwards RESET and RESET ACK between both.

Create the initial FSM that starts and stops two SS7 instances (one for
CN, one for RAN), and binds an sccp user to each.

It was decided to write OsmoBSCNAT with 3GPP AoIP support from scratch,
in a separate repository from OsmoBSC. The previous codebase was too
heavily tied into legacy SCCPlite code and had been removed from
osmo-bsc.git in Ia05dc76336a64a7f08962843b9a7cc19f2c83387.
