as mentioned in another thread before, here are my WIP patches for VC-1
interlaced B-Frame decoding.
The first patch, implementing Interlaced B-Frame header parsing, should be
pretty much complete.
The second patch, implementing MB level parsing and the actual processing
of the MBs is still lacking however.

The big part missing is MV prediction and motion compensation (something
like vc1_pred_b_mv_intfr), but i do not have the required knowledge of
either the VC-1 decoder or the general concept of MV prediction/motion comp
to implement this.
I suppose i could learn over time, but time is something i'm constantly
short on, so i didn't get anywhere with this.

If anyone wants to continue this work, you're free to do so.
