015821229f 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.

5941978e71 vp3: bfin: Transpose the IDCTs 
While this change isn't bitexact, the IDCTs weren't bitexact to
start with either.

This simplifies decoupling vp3 from dsputil.

aa8d89536d bfin: Don't use the vp3 idct functions if bitexact behaviour is expected 
In the non-bitexact mode, vp3 currently decodes to the same
frame crcs as before 28f9ab702 (and the output visually looks
correct).

88bd7fdc82 Drop DCTELEM typedef 
It does not help as an abstraction and adds dsputil dependencies.
