Fix the merge issue due to pvq. This fixes significant key frame
performance loss.

Change-Id: I5fef4648cfc9e94f63b553ac15e051a6c4d4ca13

Unify the use case of largest transform block size fetch for skip
blocks.

Change-Id: I5dd60eb74b266fa7cd7944d8f823dbdae75e90af

The rans experiment is dead. The ans experiment with the ec_multisymbol
experiment also turned on takes its place.

Change-Id: Ie9f30ec7cf73aae6b2ea580a7b1f208485a8a7a7

Remove redundant #if statements there.

Change-Id: If6e6000c76899b0c3072e741a22bc3efa7d33739

Replace repeated is_inter_block() check with a constant is_inter
variable.

Change-Id: I1215f72d5fcbf167cf5252333e7d9fbe5c9ff808

This CL doesn't change any coding behavior.
The functions modified in this CL include
choose_smallest_tx_size()
choose_largest_tx_size()
choose_tx_size_type_from_rd()
txfm_rd_in_plane()
txfm_yrd()

This change make the code cleaner and will facilitate rd_debug
implementation

* 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

Replace max_tx_size with min_tx_size for transform type decision.

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:

Only part of the changes apply in nextgenv2

- Add minimal compiler flag testing.
- Generate aom_config.c and aom_config.h. Note: hard coded
  to generic-gnu values for now.
- Still a work in progress. This will not build anything.

The initialization of transform parameters was missing, that led to a
crash in encoder.

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

This commit resolves some compiling issues due to merge.

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:
https://github.com/xiph/daala/commit/fb51c1ade6a31b668a0157d89de8f0a4493162a8

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:

 av1/common/generic_code.h

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.
