Handle the first color index in the tokenization process, along with the
other color indeices.

This patch also includes some minor refactoring changes.

Test results verify that there is no implact on compression efficiency.

In ext_tile experiment, when cm->large_scale_tile is 1, prev_frame_id can be
the same as current_frame_id, which is prohibited in reference_buffer
experiment and causes "CORRUPT_FRAME" error to be reported.

In this patch, enable/disable reference_buffer according to large_scale_tile
value, and thus make these 2 experiments compatible.

Process the intra block coding in maximum of 64x64 block unit.
This allows to simpilify the hardware design for 128x128 level
block coding.

Change-Id: I6ef1dd8549bdb53b2d2394c6aa7d61cea93686bf

This commit makes the maximum transform coefficient coding unit
64x64 for inter coded blocks. It allows the hardware design to
reuse the existing 64x64 coding pipeline for 128x128 level blocks.

Use the row and column indexes to fetch txk_type, which allows the
chroma components to derive the tx type from the corresponding luma
components. It improves the coding performance of txk-sel by 0.18%.

Added a 1-bit flag 'large_scale_tile'. If it is 0 that is the default value,
use normal tile coding in TILE_GROUPS. If it is 1, use large-scale tile
coding in EXT_TILE.

At large_scale_tile=1 case, if single-tile-decoding is required, then the
loopfilter is disabled.

Related API and unit tests were modified.

To make it compatible with frame_superres

Change-Id: Id1560e1477a09cfd27a4b4f17468be9c76d09013

This patch adds support for 4:1 rectangular blocks to various common
data arrays, and adds new partition types to the EXT_PARTITION_TYPES
experiment which will use them.

This patch has the following restrictions, which can be lifted in
future patches:

  * ext-partition-types is incompatible with fp_mb_stats and supertx
    for the moment

  * Currently only 32x32 superblocks can use the new partition types

There's a slightly odd restriction about when we allow
PARTITION_HORZ_4 or PARTITION_VERT_4. Since these both live in the
EXT_PARTITION_TYPES CDF, read_partition() can only return them if both
has_rows and has_cols is true. This means that at least half of the
width and height of the block must be visible. It might be nice to
relax that restriction but that would imply a change to how we encode
partition types, which seems already to be in a state of flux, so
maybe it's better to wait until that has settled down.

Recently, sub8x8 inter mode decition functions have been
removed from the av1 codebase, so codebase does not allow
disabling cb4x4 anymore.

This makes pvq not working simply crashing
because we had disabled cb4x4 if pvq is enabled.
Hence, pvq has been fixed for cb4x4.

Also, if pvq is enabled, disable lgt and highbitdepth in the configure.

(1) Work with var-refs to remove redundant bits in ref frame
    coding;
(2) Add a new uni-directional compound reference pair:
    (LAST_FRAME, LAST3_FRAME);
(3) Redesign the contexts for encoding uni-directional reference frame
    pairs;
(4) Use aom_entropy_optimizer to collect stats for all the default
    probability setups related to the coding of reference frames.

Compared against the baseline (default enabled tools excluding ext-tx
and global-motion for encoder speed concern) with one-sided-compound,
the coding gain of ext-comp-refs + var-refs - one-sided-compound is:
