This merge keeps our condition against w-i and h-j instead of bw and bh.
One may be more correct than the other, but I'm keeping our behaviour
here for safety reasons.

The style and formatting is merged.

The isGray() chunk is not merged as an alternative patch actually fixing

The SWS_X chunk is merged, with an additional cosmetic.

  vp9: reindent after last commit

  vp9: split last/cur_frame from the reference buffers.

This commit is a noop, we already have all these changes. Again, we will
need in the future to analyse the tiny differences between the two
repository on the vp9 files. But in the current state, it's a real pain
to do at every commit due to the huge differences (such as files split
and cosmetics).
