commit fixes a bug where wrong segment_id is used in such selection.

The macro used in assert is defined under CONFIG_VAR_TX. This fixes a
build issuse when --enable-var-tx and --enable-rd-debug are both on.

USE_TXTYPE_SEARCH_FOR_SUB8X8_IN_CB4X4 macro added to turn
tx_type search on/off for sub8x8 in cb4x4 mode.
The purpose is mainly to analyze the coding gains from cb4x4
but this later can be made into a speed feature as well.

Integerizes computation of the least squares for warped motion.
The model is restricted to only Affine. Affine seems easiest
to compute and integerize since it can be split into two 3-dim
least squares problems, as opposed to rotation-zoom which needs
a 4-dim least-squares problem to be solved.
The current implementation requires only one division per block.
BDRATE impact is mminimal. The upgrade to the affine model improves
coding efficiency but integerization also degrades efficiency a
little. Overall there is a net gain of about -0.07% BDRATE on
the lowres set.
BDRATE lowres: -1.113% with ----enable-warped-motion vs. without
(up from -1.044%).

- Move source list vars.
- Split source list vars into common/decoder/encoder sources.
- Move target definitions into function.
- Split targets into common/decoder/encoder targets.
- Update CMakeLists.txt to include test.cmake and call
setup_aom_test_targets() at the appropriate time.

It only handles the realloc constraint (preserving low elements) by
serendipity, and we don't actually rely on that behavior anyway.
Meanwhile the calls may do extra copying that gets immediately clobbered
by the callers.
Cherry-pick from libvpx:

Since we now require C99, this is undefined behavior.
Thanks to Luc Trudeau for the report and Alex Converse for the
suggestion on how to make the macro safe for all integer sizes.

This commit enables the motion vector referencing system to use
the motion information of blocks to the bottom and right of the
collocated block. This improves the compression performance by
0.3% for lowres, midres, and hdres sets.

+ inline the function directly as there was only one consumer
(get_prob())
this is an attempt to reduce the amount of branches to workaround an amd
bug. this change is mildly faster or neutral across x86-64, arm.

Merges two consecutive loops that iterated over TX_SIZES. There's no
impact to the bitstream. The 4 used as the termination threshold in the
second loop is equivalent to TX_SIZES.

When creating the CDF head, do not use 8-bit probabilities
to make the CDF tables, but load them directly.
CDF tail values are created from the ONE_TOKEN relative
probability as before.
No change to BDR.

* code the palette color index using 45 wavefront
* interleave the coeff and palette color index in
transform block level
* the above change does not change code efficiency
Details:
The 45 wavefront scan allows to compute the ctx of
the diagonal samples' indices at the same time.
Interleaving palette indices and palette residual
on a transform block basis means that the entropy
decoding and further processing of the palette
residual is not delayed by the entropy decoding
of all the color indices of the palette encoded
block.

This allows compiling a codec using the same operating path (the generic
"high-bitdepth" one), regardless of the profile of the input bitstream.
For now, keep the 16-bit (generic) pixel operating path disabled by default.

Adds the static inline function get_plane_type to convert a plane number
to the corresponding PLANE_TYPE.
There's no change to the bitstream, it only encapsulates the logic to
get the PLANE_TYPE.

Support the use of 2x2 prediction and transform block size for
chroma components. This experiment builds on top of cb4x4. It
brings back the loss in performance gains due to 4x4 chroma
component constrain. The coding gains for lowres are up from 1.5%
to 2.5%.
