vl/mpeg12: fix mpeg-1 bytestream parsing

This fixes the bytestream parsing of mpeg-1 stream, but still leaves
open a number of issues with the interpretation:
- IDCT mismatch control is not correct for MPEG-1.
- Slices do not have to start and end on the same horizontal row of macroblocks.
- picture_coding_type = 4 (D-pictures) is not handled.
- full_pel_*_vector is not handled.
