68c1e91316 vp9: improve signbias check. 
Otherwise it will still scale motion vectors, which leads to corrupted
prediction.

32b6d31ef3 vp9: don't allow compound references if error_resilience is enabled. 
libvpx (probably accidentally) clears the bits if error_res is set,
along with keyframe/intraonly. This probably wasn't the intention
(since it's local data), but it's behaviour we have to copy...

29045fbfd4 vp9: clip motion vectors in the same way as libvpx does. 
The practical effect of this is that the scaling will wrongly not be
applied to the interpolation edge (the 3/4 constants in this patch).
In other words, we clip to the pre-scaling interpolation, even though
these should be clipped post-scaling. The resulting out-of-frame MVs
are thus automatically clipped within the visible portion of the frame,
which is probably not the intention, but is unfortunately what libvpx
does, so we need to copy that behaviour.

96a58a8daa vp9: set skip flag if the block had no coded coefficients. 
This reproduces libvpx behaviour. It seems like it originally only
targeted loopfilter behaviour, but this unfortunately effects following
block contexting and thus directs bitstream sync.

d32d0593f1 vp9: disable more pmulhrsw optimizations in idct16/32. 
For idct16, only when called from a adst16x16 variant, so impact is
minor. For idct32, for all, so relatively major impact.

96d30c3495 vp9: disable all pmulhrsw in 8/16 iadst x86 optimizations. 
They all overflow in various samples that are considered valid input.

72e7553125 pngdec: set correct range 
AV_PIX_FMT_GRAY8/16 are considered YUV formats, and the color_range is
not set - so the API user will have to assume limitted range. (Unless
the API user adds a special-case for the PNG decoder.)

Just export the correct range - full range.

75fc81c831 diracdec: check that block length is valid 
In init_planes p->xblen and p->yblen are set to:
            p->xblen = s->plane[0].xblen >> s->chroma_x_shift;
            p->yblen = s->plane[0].yblen >> s->chroma_y_shift;

These are later used as block_w and block_h arguments of
s->vdsp.emulated_edge_mc. If one of them is 0 it triggers an av_assert2
in emulated_edge_mc:
    av_assert2(start_x < end_x && block_w > 0);
    av_assert2(start_y < end_y && block_h > 0);
