This fixes the coding failure when both tile-groups and ext-refs
are turned on. It clears the nightly-run unit test failure.

Removes redundant deblocking filtering operations and buffer copies,
during search for the restoration filters.
Also, makes the order of cdef and loop-restoration consistent.

With this patch, --enable-var-tx only enables recursive transform
partitioning without using rectangular transforms.
To enable use of rectangular transforms in addition, use:
--enable-var-tx --enable-rect-tx
The RD selection process is not fully tested under the var-tx flag
only. We might expect certain performance loss there.

The variables robust and nodesync appear to represent the same concept.
In order to simplify, they are merged into nodesync. This change does
not alter the bitstream as this value is hard coded to 1.

In Daala, od_pvq_rate depended on the frame type because of H/V pred.
However, H/V pred is not in AV1, as such this code can be removed.
This changes do not impact the bitstream as currently is_keyframe is
hard coded to zero.

This change improves efficiency and means that tile groups
cause negligible loss (+0.03% BDR) in the current default
encoding configurations (1 tile group no matter how many tiles)
with frame-based wrapping.
In future, when wrapper formats support tile groups, lengths
can be omitted from the last tile in every tile group.

As H/V Prediction is not implemented in AV1, pvq_theta does not need to
consider it when adjusting its parameters.
It is important to understand that the results shown here are not the outcome
of this patch but the outcome of leaving the condition in and enabling
is_keyframe. Currently, this change does not impact the bitstream as
is_keyframe is hard coded to 0 for PVQ.
The following result show that enabled for spatial intra, the H/V pred
tweaks do not yeild benefits.

In av1_selfguided_restoration, the values stored into 'dgd' are

Removes the unneeded one (encint.h) and moves everything not needed in
the header to the .c file itself, thus this commit should make including
both ratectrl_xiph.h and pvq headers without error.

Fixed the build fail in the xiphrc and daala-dist, which are tested
for inclusion in libaom__compile_experiments but produced error
as reported in above bug report.
Thanks to James Zern for reporting and suggesting how to fix.

The parallel_deblocking experiment is proposed jointly by Intel
and Microsoft. The following changes are implemented in this
experiment:
- deblocking filter order is changed to filter all vertical edges
of the whole frame followed by filtering all horizontal edges
of the whole frame
- filter length decision is made based on the transform block size
on both sides of the edge. block with smaller transform size
determines the final filter length.
- transform blocks on both sides of the edge are checked, only when
both blocks are skipped and they belong to the same prediction
block, filtering of that edge can be skipped.
- 15-tap filter and extended flat area detection are removed.
- special rule for handling 4x4 transform block on the super block
boundary in VP9 is removed.

Resolve the encoding failure when ec-multisymbol and rectangular

Adds the arguments struct HandleInterModeArgs to hold arguments that
are conditional on compiled features. This means that there are no
longer #if's in the function's argument list.
Some of the array pointers that were optional arguments have been
made array members in the new struct, but not all. This is due to the
function being called with either references to arrays that are
maintained between trying different modes OR with references to
"dummy" arrays initialized to zero. The arrays that are always used
are now members of the HandleInterModeArgs struct.

This reduces the runtime profile of pvq_search_rdo_double from 37%
to 15% and improves overall encoding speed when PVQ is enabled by ~40%.
The SIMD code is not bit accurate with the C version and introduces a
slight PSNR regression on AWCY:

Offsets for the least-squares for affine motion computation
are now set at the top left corner of the current block.

Disable the support of compound prediction modes for sub8x8 codking
blocks. Make the rate-distortion optimizations process account for
such constraints.
With the use 2x2 chroma prediction block, this makes the wrost case
number of inter predictors same as vp9. It affects the coding
gains by 0.35% for lowres, 0.17% for midres, and 0.08% for hdres.
The encoding speed is up by 10%.
