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

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://people.xiph.org/~jm/daala/pvq_demo/
- 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.

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

This commit refactors the recursive transform block partition
search process to make it support rectangular transform block size
coding.

This commit allows the partition context model to account for the
maximum transform block size of the coding block.
Change-Id: I22b91e85fff70faa974afd362ce327d3f2eda81d
Making this change in case the future implementation changes and the
compairson is no longer between single bits.
Change-Id: I94f474ce7d82febfa23cec65cbe1b9d240b42e02
Use unified transform block size and coding block size map. This
prepares for the integration of 2x2 transform block size and the
rectangular transform block size.
Change-Id: I99f51017d19aef337639b708ee9c7faedcc20935
Unify coefficient context used by different experiments. Make
block size and transform block size consistent with rest codebase.

It always returns true since the related misc_fix[1] was merged.
