The checked bitstream reader does that already. To allow parsing of
superframes split over a packet boundary, we always decode the last
superframe in each packet at the start of the next packet, even if
theoretically we could have decoded it. The last superframe in the
last packet is decoded using AV_CODEC_CAP_DELAY.
It is now bitexact with the ssse3 and sse4.1 versions of the function.

The assumption that avcodec_send_packet makes regarding decoders
consuming the entire packet is not true if the codec supports
truncated decoding mode and the truncated flag is turned on.
Steps to reproduce:
./ffmpeg_g -flags truncated \
-i "http://samples.ffmpeg.org/MPEG2/test-ebu-422.40000.pakets.ts" \
-c:v ffv1 -c:a copy -y /tmp/truncated.nut

Most decoders return the amount of data used.
This is more consistent

The arguments of av_reduce are signed, so the cast to uint64_t is misleading.

ff_parse_close expects priv_data to be the ParseContext directly and
thus doesn't work if it isn't at the beginning of OpusParseContext.

Make ff_opus_parse_extradata free allocated memory on error instead of
expecting callers to free it in that case.

This decreases the amount of computations and memory needed for analysing mpeg1/2 streams
the properties update is moved from code that is skiped if skip_frame is set
to code that is not skiped so the change doesnt loose that
from being executed
