RBS2000: re-establish any lost signalling links
Contrary to standard A-bis, in the RBS2000 case the BSC connects the signalling data links (LAPD) to the BTS. In case one of them drop, we need to attempt to re-establish them. This requires libosmo-abis with Change-Id I07f0f79e0cda09766f357032ffb4e7ad643d448a Change-Id: I710b5af5d0acbdd3febd314849340f2adb7abd80
