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.

The existing implementation had little to do with VC1.
This could be implemented by adjusting the reference frames
ithemselfs but that would make frame multi-threading difficult.

This fixes a segfault with samples that I have (both of them MPEG-TS). Looks like
avctx->codec is not being set during parsing.

The existing code is not in the right place and it should cover both
interlaced frame and field pictures.

It is currently only handled in the parser code for WMV/ASF style
header, but not the one used in the bytestream format used when
muxed into MPEG-TS as on e.g. BluRay.

Previously, it would not be read if refdist_flag was not set, however
according to the spec and the reference decoder, it should always be read.
