stream_ffmpeg: handle rtsp:// URLs by default, add lavf://

Browse Source 
Make stream_ffmpeg handle rtsp:// URLs by default, without requiring
ffmpeg://rtsp://. Previously (after removal of other rtsp
implementations) rtsp:// fell back to using HTTP, which was unlikely
to work.

Also add lavf:// as an alternative to ffmpeg:// to force the stream
implementation. Since libavformat can come from Libav rather than
FFmpeg, using the ffmpeg name in the prefix is misleading.
