Scale the block size in the active map with respect to the
effective mode_info size. This resolves an active map unit
test failure issue due to out-of-bound address access.

Directly use mbmi->mv[0] since the displacment of block center has
been calculated according to GM/WM model and stored in mbmi->mv[0].

Adds an option to disable warp when obmc is used with a
warped motion neighbor.
This change will reduce the line buffer requirement for
mode/mv information since the warping parameters no longer
need to be stored.
Results: 0.05% increase in BDRATE on lowres

Instead of using inter/intra to determine the dst buffer has
residue or not, we use dst_has_residue.
This will provide us more flexibility to do experiment.

This CL actually makes the code more complicated but it will allow
us to break the framework of searching tx_size with fixed tx_type
I will find a way to simplify the code later.

Disable OBMC mode if the current block uses compound prediction.
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.

removes some unnecessary casts and adds a few explicit uint32 ones for

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.

Resolve tokenization and bit-stream packing issues in var-tx
when the re-designed cb4x4 is enabled.

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.
