MSC side of LCLS (local call local switching) as per the 3GPP specs
3GPP LCLS allows the media stream of a call to remain locally at the BTS, if both legs of a call are within the same BTS. We should implement this in OsmoMSC, if not only to test the OsmoBSC side which we want to implement, too.

Corresponding libosmocore changes are mostly merged, there're 4 more pending patches for OsmoMSC.
N. B: current implementation is only suitable for testing due to issues with CallRef handling by transactions. This part is going to be heavily changed by intra-BSC handover work.

It's already useful enough for testing BSC-side but needs more work to properly handle HO and correctly construct GCR for all interfaces/transaction variants.
