#916: ffmpeg doen't check that udp port which it selects for incoming rtp already

Comment (by xeioex):
I've checked what other implementation of RTP/RTSP do in this case.
1) LIVE555 library (inside vlc media player)
2) gstreamer framework
Both of them just request no udp port from special range, but use port
which an OS provides.
It this case local udp ports grow sequentially and issue case doesn't
occur. Remote side after some period of time stops sending packets to old
ports.
