Results if we only disable this combination for small
block sizes are also listed.

This function was incorrectly using transform width instead of height.
The bug wasn't caught yet, because all calls to this function currently
use square transform sizes only.

This applies the same refactorings to highbd_warp_plane
which were applied to warp_plane a while ago, and lays the
groundwork for the relevant tests.

The probability of several of the symbols used for extra bits for
category 6 tokens, which as far as I can tell are legal to code,
was set to zero, and in one case even negative.

In the beginning of encoding and bitstream packing,
the frame context in common of codec is copied to the frame context
in each tile.
Initial prob and context is based on flat probability and
does not come from table at the moment.

The bd-rate change for the test set objective-1-fast
on awcy with high delay mode is:

PSNR   PSNR  HVS  SSIM  CIEDE 2000  PSNR Cb PSNR Cr MS SSIM
-0.77  -1.05      -0.74 -0.67       -0.67   -0.77   -0.88

In preparation for enabling backward updates of contexts for PVQ.
1. Default prob setting for PVQ,
which is based on flat probabilities at the moment.
2. At the end of encoding a frame, average probablities and expected values
of PVQ are copied to the frame context.

When a global translation model is found, the only 3 bits
of precision are used for the motion parameters. This case
uses a smaller precision than the translation parameters
in a global model that is rotzoom or greater.
