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).

vp3: Embed idct_permutation array directly in VP3DecoderContext

This makes the vp3 decoder less dependent on dsputil, and will aid
in making it (eventually) dsputil-independent.

x86: qpel: Move fullpel and l2 functions to a separate file

This way, they can be shared between mpeg4qpel and h264qpel without
requiring either one to be compiled unconditionally.

lavc: Make pointers to ff_cropTbl const

There's no point in these pointers not being const.

lavc: Move ff_cropTbl and ff_zigzag_direct from dsputil to mathtables

These are widely used throughout libavcodec, nothing dsputil-specific.

Change ff_cropTbl to a statically initialized table, to avoid
initializing it with a function call.
