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.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
