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

Fixed the build fail in the xiphrc and daala-dist, which are tested
for inclusion in libaom__compile_experiments but produced error

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.

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.

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%.

Integerizes computation of the least squares for warped motion.
The model is restricted to only Affine. Affine seems easiest
to compute and integerize since it can be split into two 3-dim
least squares problems, as opposed to rotation-zoom which needs
a 4-dim least-squares problem to be solved.
The current implementation requires only one division per block.

BDRATE impact is mminimal. The upgrade to the affine model improves
coding efficiency but integerization also degrades efficiency a
little. Overall there is a net gain of about -0.07% BDRATE on
the lowres set.
BDRATE lowres: -1.113% with ----enable-warped-motion vs. without
(up from -1.044%).
