Yushin Cho 77bba8d30a New experiment: Perceptual Vector Quantization from Daala
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:
 av1/common/generic_code.c
 av1/common/generic_code.h
 av1/common/laplace_tables.c
 av1/common/partition.c
 av1/common/partition.h
 av1/common/pvq.c

 av1/encoder/encint.h
 av1/encoder/generic_encoder.c
 av1/encoder/laplace_encoder.c
 av1/encoder/pvq_encoder.c
 av1/encoder/pvq_encoder.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.
