Chris Hodges 330c8f8b93 avformat: add AV1 RTP depacketizer and packetizer ...

Add RTP packetizer and depacketizer according to (most)
of the official AV1 RTP specification. This enables
streaming via RTSP between ffmpeg and ffmpeg and has
also been tested to work with AV1 RTSP streams via
GStreamer.

It also adds the required SDP attributes for AV1.

AV1 RTP encoding is marked as experimental due to
draft specification status, debug amount reduced
and other changes suggested by Tristan.

Added optional code for searching the sequence
header to determine the first packet for broken
AV1 encoders / parsers.

Stops depacketizing on corruption until next keyframe,
no longer prematurely issues packet on decoding if
temporal unit was not complete yet.
