rtp: make port range configurable, assign correct port numbers
The current implementation does not allow the user to specify a port
range in which the BTS is allowed to allocate a local RTP port. Also
the ports the BTS picks do not match the policy described in RFC3550.
An RTP Port must be at an even port number and the matching RTCP
port must be at the following (odd) port number. The BTS currently
picks random port numbers for both.
- Add a VTY command to specify a port range in which the BTS may
assign local ports.
- Pick ports as described in RFC3550.
