6892df9294 vp3: Change type of stride parameters to ptrdiff_t 
This avoids SIMD-optimized functions having to sign-extend their
stride argument manually to be able to do pointer arithmetic.

Also adjust parameter names to be "stride" everywhere.

880e2aa236 Remove all Blackfin architecture optimizations 
Blackfin is a painful platform to work with, no test machines are available
and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

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.

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

4a73fbd9c5 vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext. 
The function is only used in VP3 and VP5, so no need to have it in
DSPContext.

aeaf268e52 vp3: integrate clear_blocks with idct of previous block. 
This is identical to what e.g. vp8 does, and prevents the function call
overhead (plus dependency on dsputil for this particular function).

Arm asm updated by Janne Grunau <janne-libav@jannau.net>.

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context 
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

c23acbaed4 Don't use ff_cropTbl[] for IDCT. 
Results of IDCT can by far outreach the range of ff_cropTbl[], leading
to overreads and potentially crashes.

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.
