* changes:
Merge rd_stats only when it is valid
Let parentheses in handle_inter_mode be symmetric
Add RD_STATS into MB_MODE_INFO
Add txb_coeff_cost_map
Since PVQ's max block size equals to the max transform size,
daala's definition of OD_BSIZE_MAX was changed from 5 down to 4 to
use AV1's max trasform size 32x32. However, dering also uses
OD_BSIZE_MAX and assumes its value is 5, which caused dering
not working.

This commit is a manual cherry-pick from aom/master:
45592a39d3b00aee4d6bd70da669400017b7a5d8
Only part of the changes apply in nextgenv2

The transform functions have been refactored in nextgenv2, this commit
resolves the calls in pvq patch to use this new scheme.

Previously, do_cubic_filter would return results with the
wrong precision if the sample point was exactly aligned to
a pixel.

PVQ replaces the scalar quantizer and coefficient coding with a new
design originally developed in Daala. It currently depends on the
Daala entropy coder although it could be adapted to work with another
entropy coder if needed:
./configure --enable-experimental --enable-daala_ec --enable-pvq
The version of PVQ in this commit is adapted from the following
revision of Daala:
fb51c1ade6
More information about PVQ:

- https://jmvalin.ca/papers/spie_pvq.pdf
The following files are copied as-is from Daala with minimal
adaptations, therefore we disable clang-format on those files
to make it easier to synchronize the AV1 and Daala codebases in the future:

Known issues:
- Lossless mode is not supported, '--lossless=1' will give the same result as
'--end-usage=q --cq-level=1'.
- High bit depth is not supported by PVQ.

With RD_STATS in MB_MODE_INFO, we will be able to compare the results
from rate-distortion loop and the results from bitstream packing.

The txb_coeff_cost_map is a 16x16 map which records each single
transform block's cost from the transform block's location in 4-pixel
unit in recursive transform experiment.

Compare token cost of pack_mb_tokens/pack_txb_tokens with token cost
from rate-distortion loop. If there is any difference, dump out mode
info.

This commit replaces the offset based block index calculation with
incremental based one. It does not change the coding statistics.
