[FFmpeg-devel] [PATCH] avformat/rtpproto: add support for RTP/UDP socket reuse

It is not your fault, but the name of the option is misleading: it does
not reuse any sockets, it allows to reuse an *address* and maps to the
SO_REUSEADDR socket option. The misleading part is already in udp.c, but
I think we should avoid letting it proliferate.

Also, instead of passing this particular option, I think it would be
better to make the UDP context a child context of the RTP context, so
that options are applied recursively automatically.
