900e3af857 vp9: match another find_ref_mvs() bug in libvpx. 
If we find a second non-sub8x8 motion vector for a non-first sub8x8
block, and the clamped value is identical to the first non-sub8x8
motion vector, then the resulting nearmv motion vector is forced to
zero.

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.
