This can be re-added after aligning AOM's ANS with nextgenv2's ANS.
This partially reverts commit 3829cd2f2f9904572019aa047d068baeee843767.

Previously, only the motion vectors were being stored. This caused
a mismatch in the global motion experiment, which needs this
mode information to decide whether or not to use the gm parameters
in reconstruction.

av1_clpf_frame() was always called with the same src and dst,
so we only need one argument and the code supporting different
src and dst was removed.

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.

Refactor to streamline the number of profiles needed, in
preparation for the next steps.
NO change in performance.

Disable rect_tx because we only support 4x4 Walsh-Hadamard transform
in lossless mode.
Fixes failure in ./test_libaom --gtest_filter=*Large*ScreencastQ0/1
Configuration: --enable-experimental --enable-var-tx --enable-rect-tx

Also adds hooks to choose different profiles for UV and intra.

Remove VP10 style bitreader and bitwriter wrappers
Rename av1_ans_test to match aom/master.
Migrate bitreader to the interface from aom/master
Includes a major refactoring/enhancement to support
tile-adaptive switchable restoration. The framework can be
readily extended to add more restoration schemes in the
future. Also includes various cleanups and fixes.
Specifically the framework allows restoration to be conducted
on tiles such that each tile can be either left unrestored, or
use bilateral or wiener filtering.
There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
Further enhancements will be added subsequently to improve coding
efficiency and complexity.

this matches style guidelines and stabilizes successive runs of
clang-format across the tree. remaining types should be address in
successive commits.

This allows for a clean subtraction of 1 along the transform
matrix diagonal and also makes the order of the parameter list
a little more intuitive.

Bitstream syntax:
For a rectangular inter block, 'rect_tx' flag is sent to indicate if
the biggest rect tx is used. If no, continue to decode regular
recursive tx partition.
Change-Id: I127e35cc619b65acb5e9a0717f399cdcdb73fbf0
Uses an array to map block sizes, y tx sizes, and subsampling
factors to various transform sizes for UV.
Results improve by 0.1-0.2%

This patch completes the global motion experiment
implementation. It modifies the format of the motion
parameters to use the mv union to facilitate faster
copying and checks for parameters equal to 0 that occur
frequently in rdopt. The rd decisions for the global motion experiment
have also been added to rdopt.
