vp6: Support cropping to AVCodecContext.width/height
...
In these cases, there is no extradata but only the properly set
width/height values by the demuxer.
This makes sure VP6 in F4V files is cropped properly.
This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f515091
.

vp3: Use full transpose for all IDCTs
...
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.
Also remove the unused type == 0 cases from the plain C version
of the idct.
