http://fate.ffmpeg.org/ runs the tests often enough that any issue
should be caught (with the prng seed to reproduce it), so that's
probably fine.

const

[..]

Could be declared and initialized at the same time.

I unfortunately don't know enough about VP9 to comment on most of the
logic or numerical values chosen, but I'd say go ahead and push if
nobody objects.
