FLAC streams originating from the FLAC encoder send updated and more
complete STREAMINFO metadata as part of the last packet, so write that
to CodecPrivate instead of the incomplete one available in extradata
during init.

This will allow us to write updated stream information not available
during write_header().

A negative extradata size for example gets passed to memcpy in
avcodec_parameters_from_context causing a segmentation fault.

If realloc fails, the pointer is overwritten and the previously allocated
buffer is leaked, which goes against the expected behavior of keeping the
packet unchanged in case of error.

This makes av_stream_add_side_data() consistent with av_packet_add_side_data().

Functionally similar to av_packet_add_side_data(). Allows the use of an
already allocated buffer as stream side data.

Video doesn't exit ffmpeg on error anymore, and audio now prints an
error.

It makes no sense for this code to be inside the video filter loop, and
the frame sample aspect ratio is even set unconditionally a few lines
above.

This avoids unneeded computations

Fixes remuxing apng streams coming from the apng demuxer, which sends extradata
during init.
Signed-off-by: James Almer <jamrial@gmail.com>

This reverts commit e0c6b320.

Said commit changed the behavior of the demuxer and decoder in a non
backwards compatible way.
Demuxers should make extradata available at init if possible, and send
new extradata as side data within a packet if needed.

A better fix for the remuxing crash will follow.

  FATE: add a test of H.264 SEI recovery in an intra refresh stream

Our H264 decoder drops 3 frames from the beginning of the stream, but
all frames after those match, hence the difference in the fate test.
