rtp_proxy: add RTP_LOOPBACK mode for local loop back
This will echo back all voice received on the socket back to the same
socket/subscriber.
If we mark a socket as LOOPBACK at the BSC, we don't yet know a priori
which source IP/port the BTS side of the socket will have, so we can
only bind our local IP+port. Only once the first message from the
BTS arrives at the BSC rtp_proxy, we know the source and should do a
connect() to that remote address.
The rtp_proxy has no idea when a call is disconnected, so the loopback
mode only works for the first call, but no subsequent calls.
This patch compares IP/PORT of the BTS side of the RTP flow and issues a
new connect only if it is not the current remote address.
