  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).

These values are defined to be 32bit in the specification,
so it makes more sense to store them as fixed width.

Allows to get a more realistic total bitrate (and estimated file size)

assumed.

Adds an internal helper function for bitrate guessing.
