d1d9b0813a avcodec/libdav1d: clear the buffered Dav1dData on decoding failure 
Should ensure avcodec_send_packet() doesn't return EAGAIN in scenarios where it's not
meant to (e.g., ffmpeg_dec.c where avcodec_receive_frame() is called in a loop to drain
all produced frames before trying to submit more packets).

Fixes ticket #11377.

d8d0175d3a avformat/flvenc: implement support for multi-track video 
Based on enhanced-rtmp v2 spec published by Veovera:
https://veovera.github.io/enhanced-rtmp/docs/enhanced/enhanced-rtmp-v2

This implementation maintains some backwards compatibility by only
writing the track information for track indices > 0. This means that
older FFmpeg versions - and possibly other software - can still read the
first video track properly and skip over unsupported packets.

af6d52eec6 swscale: use 16-bit intermediate precision for RGB/XYZ conversion 
The current logic uses 12-bit linear light math, which is woefully insufficient
and leads to nasty postarization artifacts. This patch simply switches the
internal logic to 16-bit precision.

This raises the memory requirement of these tables from 32 kB to 272 kB.

All relevant FATE tests updated for improved accuracy.
