Remove the asserts in rd_pick_partition(), which check
whether the sum of distortions of sub8x8 partitions matches to
the 8x8 distortion measured in final reconstructed 8x8 pixels,
because the sum of the sub8x8 distortions returned from rd_pick_sb_modes()
is sometimes different from what is measured with final reconstructed 8x8 pixels.

The asserts have been provided for the purpose of sanity check with PSNR
and triggered with "--enable-dist-8x8=1" encoder option.

Properly store and update the luma component result in the key
frame rate distortion optimization process for chroma component
prediction. The txk-sel provides 0.15% gains for key frame coding
on top of lv-map/multi and all other default experiments.

Change-Id: I694860607b318d0a84333ed928d3de85c7676623

The cfl route needs the reconstructed luma pixels in the chroma
RD search. Replace an extra route of txfm_rd_in_plane with the
use of av1_encode_intra_block_plane to directly write out the
needed luma pixels in the key frame rate-distortion optimization
process.

The compression stats remain identical. The key frame encoding
speed is on average 3% faster for a few tested 1080p clips.

If the transform block selects a transform kernel type that makes
it all zero coefficients and hits the best rd cost, store such
decision and force the transform block to be coded as all zero
block in the final coding pass. This makes txk-sel improve the
kf coding performance by 0.15% now.

This reverts commit 2944f9d1.

Reason for revert: it breaks encode+decode with error message:  
"Warning: Failed to decode frame 1: Bitstream not supported by this
decoder".

For partition types pruning in ext-partition-types, horz_rd and
vert_rd are used to store the RD costs for the two blocks in
horizontal partition and vertical partition. Hence array size of
2 is sufficient for either array.

This experiment has been adopted, we can simplify the code

The quantize_b functions for the new-quant experiment currently
do not use the zbin_ptr used in the baseline quantize_b functions.
This fixes the new-quant functions to improve performance of the
optimize=2 setting.

when 5 tap filter(filter6) was introduced for chroma plane, it reads 6 pixel
lines/columns and modify 4 pixels. However, for the filter mask
calculation, it still use the original filter mask calculation function
for 7 tap filter(filter8), i.e, read 8 pixel lines/columns to check whether the
edge sould be filtered or not. This change updates the filter mask
calculation to make it consistent with the filering operation to only
read 6 pixels for filter mask calculation.

To calculate wmmat[2] to wmmat[5], we don't need the absolute
coordinates which include the global offset components. Hence,
while finding samples, we only need to gather the relative coordinates
that are the neighbor block center point's coordinates relative to the
left-top pixel of current block. This patch won't change bitstream.

The cos bits and 2d tx algorithms are also adjusted accordingly to
meet the 32-bit limit.

When the last coeff is at level 1, do not overwrite the low_qc
with qc. This avoids the use of a wrong value to compute rd_eob_low
later in the same function.

The original sample selection process involves finding best 8 sorted
samples according to motion vector difference(MVD) between neighbor
block and current block, and then trimming samples. To reduce the
complexity, use the current block width/height as the MVD threshold,
and trim the samples without sorting.

This gives slightly less gain than the original method.
