This will help in supporting old versions, e.g. version 3.93 uses the same
range coder but different predictor and version 3.82 uses different range
coder and predictor. Also this should not make decoding newer versions slower
by introducing additional checks on versions.

This allows demuxing and muxing of CAVS TS streams.

There are never any packets for those streams.
Fixes an infinite loop with -attach.

This allows reporting missing features and requesting samples from
all libraries in a standard way; with a simplified API.

The tool nowadays supports more than one track per file,
this makes reading the code slightly less confusing.

AVCodecContext release_buffer() shall be NULL for audio codecs using
get_buffer. The backward compatibility code hence have to check before
calling it.

Fixes memleaks when frame mt is used and the decoder is not flushed at
the end.

The svq3 decoder does not call ff_h264_frame_start() anymore.

The h264 decoder does not use mpegvideo anymore. The svq3 decoder only
uses ff_draw_horiz_band().
