Description

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.

Checklist

LCLS implementation in OsmoMSC
test suite for LCLS in MSC
jenkins integration of test suite

Shall I take this as well? Seems like next logical step to be able to test LCLS with actual hw.

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.
