b1bb8fb860 svq1dec: check that the reference frame has the same dimensions as the current one 
They can be different if the last keyframe failed to decode correctly.
Fixes possible invalid reads in such a case.

6add6272da fate: Set the bitexact flag for vp3/vp5/vp6 tests 
This is required since there are bit-inexact implementations
of the vp3 idct (for bfin).

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.

c2c9801bc9 lavfi: deprecate avfilter_graph_add_filter(). 
Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

bc1a985ba0 lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). 
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

38f0c0781a lavfi: merge avfiltergraph.h into avfilter.h

62844c3fd6 h264: Integrate clear_blocks calls with IDCT 
The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700
to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb
(in the decode_slice loop) goes from 1759 to 1733 cycles on the clip
tested (cathedral), i.e. almost 30 cycles per mb faster.
