This experiment removes the tx_mode flag from the uncompressed frame
 header and instead always uses a constant value.

The new motion mode "NCOBMC_ADAPT_WEIGHT" cannot be used
in the motion search loop as it requires all mvs from the
neighboring blocks. This patch add a wrapper to skip checking
this mode during mv search.

This required moving the CDEF and lr signaling in the
uncompressed header to after segmentation is signaled.

The all_lossless logic was factored out into onyxc_int.h.

When EC_ADAPT is enabled, this patch removes all probability tables
 associated with coding intra tokens.
This commit has no change to metrics.

When EC_ADAPT is enabled, this adds const av1_intra_mode_ind and
 av1_intra_mode_inv arrays and removes the av1_intra_mode_tree const.

Support the transform block kernel coding for rectangular
transform block size in var-tx. This integrates txk-sel with
var-tx.

Define the syntax and entropy coding templates for
NCOBMC_ADAPT_WEIGHT. The actual values of the default
probabilities and the index tree structure need to
be fine tuned.

In this experiment all mv's in a superblock are sent
first as in the ncobmc case.

Patch b1bedf5f converted the three writes in bitstream.c that
specify an extended transform from using av1_write_token (encoded with
probability trees) to aom_write_symbol (encoded with CDFs).

That patch fixed up the two reads in decodemv.c but didn't fix up the
corresponding read in decodeframe.c. This patch does so.

The patch also fixes up a write of a (non-extended) transform when not
CONFIG_EXT_TX and the corresponding read.

mi[0] is not set properly when encoding all mvs in a
super-block first. After this patch NCOBMC can function
properly.

Adds an option bit in the bitstream syntax to allow chroma to
have restoration tilesize that is coupled to luma based on
subsmapling of the color components.

This is meant to ease encoder hardware implementation.

cb4x4 itself should not require these sizes.

This simplifies compatibility with other experiments, since we can
first make them work with cb4x4 (which is now on by default), and
then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
separate steps.

Encoder and decoder output should remain unchanged.

When writing the compressed header, prob_diff_update() was called
for compound_type_prob[] for every defined block size, even though
luma never uses block sizes smaller than 4x4.

This fixes is_any_masked_compound_used() and
is_interinter_compound_used() to properly return 0 for chroma-only
block sizes, and then uses these functions to guard the probability
updates in write_compressed_header() and read_compressed_header(),
the same way the actual compound type values are guarded in
read_inter_block_mode_info() and pack_inter_mode_mvs().

The tool of ext-comp-refs adds the uni-directional compound reference
prediction. In details, 3 pairs of uni-direcitonal compound references
are added for the comp ref prediction:
(LAST_FRAME, LAST2_FRAME),
(LAST_FRAME, GOLDEN_FRAME), and
(BWDREF_FRAME, ALTREF_FRAME).

This new tool of ext-comp-refs will eventually overwrite
one-side-compound and have the two coding tools to merge to one.

It achieves -0.35 ~ -0.55% coding gains in BDRate, compared against
AV1 baseline with the default experiments on, but without
one-sided-compound. It achieves -0.2% ~ -0.3% coding gains when
one-sided-compound is on. It achieves larger gains on higher
resolution.

RESIZE_SCALE_DENOMINATOR and SUPERRES_SCALE_DENOMINATOR were two
constants with the same value that did essentially the same thing.

This patch merges the two into SCALE_DENOMINATOR for simplicity's sake.

Encoding with literals costs at most 0.8 bit per frame or
tile group for the identity type, and saves bits for other

Now the single ref comp mode should work with WEDGE and
COMPOUND_SEGMENT. For motion_var, the OBMC_CAUSAL mode uses the 2nd
predictor if the neighboring block is single ref comp mode predicted.

This patch removes the mode of SR_NEAREST_NEWMV and leaves four
single ref comp modes in total:

SR_NEAREST_NEARMV
SR_NEAR_NEWMV
SR_ZERO_NEWMV
SR_NEW_NEWMV

This patch implements the post-encode and post-decode upscaling for the
frame superresolution experiment to work.

Upscaling happens after cdef and before loop restoration.

For now, this patch forces on random-superres.

The patch also cleans up some broken rate control hooks from VP9
days, to be brought back later when the resize and superres tools
are stable.

Change-Id: If0a8f69224dfaa0f4ae7703bd429ea2af953c7a6

Check the availability of the reference frames at the frame level at
both encoder and decoder, and if a reference frame is not available
for a specific video frame, remove the signaling of such reference
frame info at the block level.

This patch adds the consideration of the bit saving inside the RD
optimization loop.
