Change-Id: I8f6dff99e413b799bed67ad0d5ecafc6c0197e22

This patch adds a decoder control that exposes frame data via a simple
 callback.

1. Adds a limit on number of candidate samples used for the
estimation.
2. Adds a limit on max mv magnitude for use in the least-squares
3. Makes some of the internal variables 32-bit.

Impact on coding efficiency in the noise range.

Since the tested functions are always forced inline in regular use,
ASM_REGISTER_STATE_CHECK doesn't make sense on this level (the test
should rather be applied to unit tests checking functions making use
of these inlined functions).  The test fails on Win64 because the
Win64 ABI requires xmm6 to xmm15 to be preserved across function
calls, but the ABI is only relevant for non-inlined functions.

In av1_selfguided_restoration, the values stored into 'dgd' are
unnecessarily rounded twice. This patch replaces this by a single
rounding operation.

Removes the unneeded one (encint.h) and moves everything not needed in
the header to the .c file itself, thus this commit should make including
both ratectrl_xiph.h and pvq headers without error.

Fixed the build fail in the xiphrc and daala-dist, which are tested
for inclusion in libaom__compile_experiments but produced error
as reported in above bug report.

Thanks to James Zern for reporting and suggesting how to fix.

The parallel_deblocking experiment is proposed jointly by Intel
and Microsoft. The following changes are implemented in this
experiment:

- deblocking filter order is changed to filter all vertical edges
  of the whole frame followed by filtering all horizontal edges
  of the whole frame

- filter length decision is made based on the transform block size
  on both sides of the edge. block with smaller transform size
  determines the final filter length.

- transform blocks on both sides of the edge are checked, only when
  both blocks are skipped and they belong to the same prediction
  block, filtering of that edge can be skipped.

- 15-tap filter and extended flat area detection are removed.

- special rule for handling 4x4 transform block on the super block
  boundary in VP9 is removed.

Change-Id: Ic34dee1dc707d9faf6a3ae250bfe39b60bef3438

Adds the arguments struct HandleInterModeArgs to hold arguments that
are conditional on compiled features. This means that there are no
longer #if's in the function's argument list.

Some of the array pointers that were optional arguments have been
made array members in the new struct, but not all. This is due to the
function being called with either references to arrays that are
maintained between trying different modes OR with references to
"dummy" arrays initialized to zero. The arrays that are always used
are now members of the HandleInterModeArgs struct.

This reduces the runtime profile of pvq_search_rdo_double from 37%
to 15% and improves overall encoding speed when PVQ is enabled by ~40%.
The SIMD code is not bit accurate with the C version and introduces a
slight PSNR regression on AWCY:

  PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000

Using 8-bit weights gives similar results as 12-bit, with only noise
level difference. Here's what 8-bit looks like compared to 12-bit:

Disable the support of compound prediction modes for sub8x8 codking
blocks. Make the rate-distortion optimizations process account for
such constraints.

With the use 2x2 chroma prediction block, this makes the wrost case
number of inter predictors same as vp9. It affects the coding
gains by 0.35% for lowres, 0.17% for midres, and 0.08% for hdres.

The encoding speed is up by 10%.
