Change subject: add handover_2G suite, with handover.py test
......................................................................
add handover_2G suite, with handover.py test
Via VTY, handover two lchans of a voice call from bts0 to bts1 and back.
New scenarios/bts1-* allow selecting various types for bts1,
complementing the already existing files for selecting bts0.
