This experiment implements the idea of the uniform tri-prediction,
which adds a 3rd inter prediction on top of the existing compound
inter bi-prediction. The final predictor for an inter-coded block is
the average of the compound bi-predictor and the third predictor,
which is indentified by a third reference frame and a third motion
vector.

This fixes the following mismatch bugs:
* At the bitstream level, the decoder would not read the delta_qindex
information for supertx blocks, but the encoder always sent it,
leading to the encoder and decoder becoming misaligned.
The delta_qindex information is still required for supertx blocks,
so change the decoder to read it.
* In addition, the quantizer was not properly adjusted for supertx
blocks at the decoder. We copy the quantizer setup code from
non-supertx blocks.
Since this does not change the encoder, it should not have any
quality impact.

rd_pick_palette_intra_sby() was being passed a dummy 'best_mbmi' in
one case, and later that dummy value could be assigned to 'mbmi'
causing invalid values in 'mbmi'.
This bug was introduced by:

Allow the above combination of experiments to work together
correctly, fixing an encode/decode mismatch bug when they
were all enabled.
This change causes build_masked_compound(_highbd) to only
ever be called if CONFIG_SUPERTX is off, so wrap these functions
in an '#if !CONFIG_SUPERTX' block.

The issue was that:
- We call av1_setup_pre_planes() when this is not an intra-only frame,
but,
- But, we do motion vector search for any frame other than first frame
Doing both of these only when this is not an intra-only frames makes
logical sense and fixes the crash too.
This also avoids doing motion search for intra-only frames in the first
pass.
Verified that there is no change in compression performance for video,
as well as when forcing all keyframes.

Preparation for merging EOB into multi-symbol encoding.
The more_data flag for the first position is moved
out of the loop, and for remaining positions is
moved in with the previous coefficient. This way it
can always be associated with the previous non-zero
coefficient.

- Added comments for some tables and #defines for clarity.
- Renamed some variables to ensure we use "color_index" instead of
"color" for palette color index related variables.

This commit makes the daala-ec work in the cb4x4 mode. As compared
to --enable-experimental, --enable-experimental --enable-cb4x4

Now that we have small number of contexts (5), use hash multipliers
(instead of base 11), so that color context hash is within a small
range. This allows us to use a lookup table to get color context
instead of a for loop.
Output bitstreams are bit-exact, so no change in compression.

This reduces the complexity in a number of ways:
- We need just 3 neighbors instead of 4.
- Possible contexts reduce from 16 to 5.
- On hardware side, getting the contexts for a whole block will be more
parallelizable.
At the same time, compression performance improves very slightly:
- Screen-content set (videos) (Google): BDRate improved by 0.32
- screenshots set (images) (AWCY): PSNR improved by 0.62:

When the functions were added in
https://aomedia-review.googlesource.com/6545 they were not restricted to
x86_64 builds.
Fixes "undefined reference to
`aom_highbd_convolve8_add_src_sse2'" for --target=x86-linux-gcc
Also remove SSE2 specializations from
`aom_highbd_convolve8_add_src[_horiz/_vert]`, since those functions
don't actually have SSE2 versions (this was left in by accident
in the original patch).

If part of a block falls outside right and/or bottom image boundary,
then only store tokens for the part of it within the boundary.
Also, consider only the part of the block within the boundary when
calculating the number of colors in the image, deciding the base
colors for palette, RD calculation etc.
The part of color map corresponding to pixels outside the image
boundary is padded with color indices copied from same row/column.
This behavior is similar to how pixels outside the boundary are padded.
For screen_content set, this is improves compression performance by
0.038 overall. One clip, in particular, has a significant gain of 0.8.

Creates the PVQ_SKIP_TYPE enum to encapsulate the different types of
skipping that can be signaled by PVQ (i.e. skip: AC, DC or both).
There is no impact on the bitstream. However, the decoder will now emit
an internal error if the decoded skip flag is out of range. The
block_skip variable is also renamed to ac_dc_coded as it stores the same
information.
