Change subject: Support control connection status query for a particular MSC.
......................................................................


Support control connection status query for a particular MSC.

Add a new control command 'msc.N.connection_status' which can be used
to query the connection status of a particular MSC with number N.

Keep the old control command 'msc_connection_status', which always
queries MSC 0, for backwards compatibility.
