svq1dec: check that the reference frame has the same dimensions as the current one

They can be different if the last keyframe failed to decode correctly.
Fixes possible invalid reads in such a case.

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.

While this change isn't bitexact, the IDCTs weren't bitexact to

This simplifies decoupling vp3 from dsputil.
