IuCS: send RANAP CommonID
Add libiu function to send a CommonID message down a UE connection, iu_tx_common_id(); add also a corresponding stub to libiudummy for linking with tests. Add libmsc function msc_tx_common_id() to call the above. Add this mostly to clearly indicate in msc_ifaces.h that libmsc is calling out of the MSC; also to do conn->via_iface checking. Call msc_tx_common_id() after ciphering is established, in _gsm48_rx_mm_serv_req_sec_cb()'s GSM_SECURITY_SUCCEEDED case. Change-Id: I576ddd5bbabfc989149debd2f8a9743db6d26043
