Merges two consecutive loops that iterated over TX_SIZES. There's no
impact to the bitstream. The 4 used as the termination threshold in the
second loop is equivalent to TX_SIZES.

When creating the CDF head, do not use 8-bit probabilities
to make the CDF tables, but load them directly.

CDF tail values are created from the ONE_TOKEN relative
probability as before.

* code the palette color index using 45 wavefront
* interleave the coeff and palette color index in
  transform block level
* the above change does not change code efficiency

Details: 
The 45 wavefront scan allows to compute the ctx of
the diagonal samples' indices  at the same time. 
Interleaving palette indices and palette residual
on a transform block basis means that the entropy
 decoding and further processing of the palette 
residual is not delayed by the entropy decoding 
of all the color indices of the palette encoded 
block.

This allows compiling a codec using the same operating path (the generic
"high-bitdepth" one), regardless of the profile of the input bitstream.
For now, keep the 16-bit (generic) pixel operating path disabled by default.

Adds the static inline function get_plane_type to convert a plane number
to the corresponding PLANE_TYPE.

There's no change to the bitstream, it only encapsulates the logic to
get the PLANE_TYPE.

Support the use of 2x2 prediction and transform block size for
chroma components. This experiment builds on top of cb4x4. It
brings back the loss in performance gains due to 4x4 chroma
component constrain. The coding gains for lowres are up from 1.5%
to 2.5%.

Since gm_get_motion_vector is trying to give a motion vector for
"the frame as a whole", it makes more sense for it to calculate
the motion of the *center* of the block rather than the top-left
corner of the frame.

In theory, this change should also help the encoder make better
decisions on when to use global motion. It avoids an issue
where, early in the frame, NEARESTMV looks like a good way to use
the global motion vector *without* paying the rate cost applied
to the first few global motion blocks in each frame. This seems
to lead to a better overall result.

Resolve a rare enc/dec mismatch issue triggered by the 4x4 chroma
block size in sub8x8 block coding.

To avoid using 2x2 chroma block size, it always uses the top-left
4x4 luma block coding information to predict the 4x4 chroma block.
The rest 3 4x4 luma blocks will be coded independently without
coding the collocated chroma blocks.

The compression performance gains are 1.45% for lowres set (down
from 2.4% of the original cb4x4 design).
