7d039e70a5 wavpack: extract channel information from the bitstream 
This way we don't require the caller to parse the block header. It also
allows the channel configuration to change mid-stream.

2cf5d29110 indeo4: reuse context block VLC for band instead of defaulting 
Currently if no custom block VLC is specified for band, a default block VLC
will be used, while the global block VLC stored in the context should be used
instead.

This fixes decoding of one sample I have.

6647aa0426 indeo4: add missing Haar and slanted transforms 
That involves fixing INV_HAAR4() macro and changing it to work with different
input and output like INV_HAAR8() instead of in-place transform.

1be175f929 vc1dec: Handle top and bottom blocks in vc1_mc_4mv_chroma4() differently if needed 
Now it can use different references for those blocks and even use
averaging.

This fixes several chroma artifacts in several videos.

28243b0d35 vc1dec: Redesign the intensity compensation 
Use the intensity-compensated reference frame for subsequent
fields/B-frames.

Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following
dependent frames.

93b1281264 vc1dec: Shuffle field MVs after decoding, not before 
This simplifies the code since copying MVs to the reference is not needed
anymore (and maybe something about fixing artifacts).

Also remove the unused mv_f_last.

Fixes a small number of artifacts in black_screen_VC-1.mkv
and several more artifacts in other videos.

9b6f47c448 matroskadec: export full wavpack blocks. 
This allows us to get rid of demuxer-specific hacks in the decoder and
will allow streamcopy from matroska once we have a wavpack muxer.

5074f4545c wavpack demuxer: export full wavpack blocks. 
Currently the demuxer shaves the blocks and exports only the
information that is useful to the decoder.

Exporting the blocks just as they are stored is simpler to understand
and will make remuxing wavpack easier.

be reallocated after a frame size change. Since we have now reference
counted buffers we can unref the buffers immediately.

db347280eb vorbis: fallback to normal division instead of crashing 
The use of ff_inverse speeds up slightly arches + compilers that
do not provide a division faster than the whole machinery, such
as ppc32 + gcc4.7, but has operational limits.

Drop the always-enable assert and provide a fallback.
