Use new H264Ref.reference field to track field picture flags. The
H264Picture.reference flag in DPB is now irrelevant here.

This is a regression from git commit d8151a7e, and that affected
multiple interlaced video streams.

The pixel buffer base address is never unlocked this causes
a bug with some pixel format types that are produced natively
by the hardware decoder: the first buffer was always used.
Unlock the pixel buffer base address fixes the issue.

Using the internal DXTC routines brings support for non multiple of 4
textures. A new test is added to cover this feature. Hashes differ
since the decoding algorithm is different, though no visual changes
have been spotted.
