bsc: Test suite for CBSP (Cell Broadcast Service Protocol)

In this testsuite, we simulate BTS and CBC by attaching to RSL and CBSP
protocol interfaces of the BSC.  We then issue a variety of CBSP
commands to the BSC and check for corresponding action on both the BTS-
facing RSL as well as responses on the CBSP side.
