enable CODEC_CAP_DELAY to flush any remaining frames in the buffer.

Stop decoding when the FN_QUIT command is found so that a trailing seek table
isn't decoded as a normal frame.

decode all channels in the same call to avcodec_decode_audio3() so that
decoding will not stop after the first channel of the last frame.

Updated FATE reference. More valid audio is now decoded.

decode_subframe_lpc().

just set data_size to zero.

fixes incorrect bitrate reporting and potential misreporting of the number of
channels.

Having it there forces decoding of a frame in order to get frame_size, but it
is not really needed for proper demuxing or decoding.

The first timestamp should be negative due to delay.
Also, do not set AVCodecContext.frame_size unnecessarily.

Using AVCodecContext.frame_size is not reliable.

This avoids some unused variable warnings with YASM disabled.

This is done conditional to the libavcodec version to avoid ABI breaks.

This fixes 'make checkheaders' on non-W32THREADS systems.

Deprecate avcodec_get_context_defaults/avcodec_get_context_defaults2

Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

Trivial replacements with sed are done in this commit:
sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'

It takes a codec parameter, thus enabling codec-specific defaults.

When scaling backward predicted MVs in second B-field, the scaling table is
opposite of that for P field pictures; i.e. first field P table will be used as
second field B table and second field P table will be used as first field B
table. This is not documented in the spec, but exists in the ref. decoder.

This fixes SA10139.

Use the native libx264 options and rename all the preset to use
the avpreset extension.
