- 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.

When CONFIG_OS_SUPPORT is not enabled the aom_timer timer function
stubs cause unused parameter warnings. This comments out the arg
names and silences the warning.

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.c
 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.

The OD_DERING_VERY_LARGE values are now explicitly copied to the buffer instead
of being read from the line buffer when we're on the edge of the frame. This
will make it possible to make the line buffer 8-bit for non-high-bitdepth.

Upsampled references currently increase the size of references by
64 times. This patch limits the memory used by the encoder to
about 3GB when encoding high bit depth content.

This should be re-evaluated in the future, if doing 8-tap
resampling in the motion search becomes reasonably fast, or if
the upsampled references are reduced in size (by omitting some
subpel positions and interpolating them instead).

Start adding cmake build support. This is based on the generic-gnu
target and will not build anything. It simply produces a project file
(when generating for a IDE) that can be loaded and that allows for
interaction with (most of) the aom sources used in a generic-gnu
build.

Notable missing pieces:
- flag testing
- config generation
- experiment configuration
- enable/disable encoder/decoder
- aomenc/aomdec
- all third party library build integration
- all tests

As compared to ref-mv, the results of this integration are:
low-delay BDR gain: 0.03%
High-delay BDR gain: 0.01%
memory/memory bandwidth saving: 40%
local memory/gate count saving: 20%

This commit fixes the top-right reference block location for block
sizes above 8x8. It improves the coding performance of ref-mv:

lowres 0.08%
midres 0.15%
