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.
