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.

None of these symbols should be accessed directly, so declare them as

905ef0d064 VP5/6/8: eliminate CABAC dependency 
Create a custom table for VP5/6/8's renorm to avoid depending on H.264's.
Saves one instruction in the arithmetic decoder as well.

5e1ba34bbb VP56: move vp56_edge_filter to new VP56DSPContext 
Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers.  The new
function pointers enable optimised implementations of the filters.

4% faster VP6 decoding on Cortex-A8.
