  vc1dec: Shuffle field MVs after decoding, not before
Merged-by: Michael Niedermayer <michaelni@gmx.at>

the float conditions are largely changed to check the DWT
instead of the bitexact flag, which previously was wrong
(DWT53 is always int)

The ist->pts value at this point does not necessarily match the actual packet
pts, which is what should be used to decide whether to discard the packet.
Without this change, some video packets that have pts on or after the start
time are getting discarded when they should not be.

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.
Signed-off-by: Martin Storsjö <martin@martin.st>

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.

Conflicts:

Merged-by: Michael Niedermayer <michaelni@gmx.at>

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.

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.

We don't know whether it will be float until we look at the data.
