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.

Previously, we assumed that av1_init_plane_quantizers is always called with
segment_id == xd->mi[0]->mbmi.segment_id (and use the latter to derive the value
of 'qindex' to use in the quantizer). But this is no longer true when supertx
is enabled. This patch instead remembers the value of 'qindex' derived from
the latest call to av1_init_plane_quantizers and uses that directly.

This CL will facilitate adapt_scan experiment.
In adapt_scan experiment, dynamic scan order will be stored in
AV1_COMMON

Plus a small code clean up. The experiment of EXT_REFS, compared against
the baseline, using Overall PSNR, now obtains a gain on lowres as:
Avg: -5.818; BDRate: -5.653
Compared against the previous EXT_REFS results on lowres, a tiny gain is
obtained as:
Avg: -0.047, BDRate: -0.063
(1) 780952 Add encoder first pass support to bi-prediction in EXT_REFS
(2) f91498 Add pred prob handling for new references in EXT_REFS
(3) e91472 Add decoder support for bi-direct prediction in EXT_REFS
(4) 0dbac9 Add encoder support to new references in EXT_REFS
(5) ad70cc Remove hard-coded number for EXT_REFS
(6) 9c1e2f Add the use of new reference frames at encoder in EXT_REFS
(7) 6d4fde Add the experiment flag of EXT_REFS

While we are at it:
- Rename some variables to more meaningful names
- Reuse some common consts from a header instead of redefining them.

Currently the patch does not have any impact on the RD performance. The
fix could however potentially help on the next step of work, especially
when the extra altref frames allow non-zero temporal filtering strength
and their corresponding OVERLAY frames, i.e. the INTNL_OVERLAY frames
are being added.

Refactor to streamline the number of profiles needed, in
preparation for the next steps.
NO change in performance.
