Passes Source-Specific Multicast parameters read from an sdp file through to the UDP socket code,
allowing source-specific multicast streams to be correctly received. As an integral part of this
change, additional checking (currently only enabled in the case of SSM streams, but probably
useful in similar scenarios) has been added to the RTP protocol handler to distinguish UDP packets
arriving from multiple sources to the same port and process only the expected packets
(those transmitted from the expected UDP source address). This resolves an issue identified
when multiple instances of FFmpeg subscribe to different Source-Specific Multicast streams
but with each sharing the same destination port.

There is no record of this ever being used at all, anywhere,
since the feature was added in 2effd274.

This gets rid of extra linker tricks just to support a feature
that isn't used, simplifying portability to other platforms.

Fix "Value 0.000000 for parameter 'srch' out of range"
error message when source or destination height is 1.

Note: since the av_opt_set_int() calls are not checked for
failure and the interlaced scalers are not actually used,
this error has no consequence apart from a frightening message
in the log.

It's the official (or recommended) name for comment/description entries.
