This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

significantly speeds up file generation.
the goal of this change is to convert rtcd.sh to perl as directly as
possible to allow for simple comparison. future changes can make it more
perl-like.

Filter out files ending in _neon.c and append .neon so the Android build
system knows to apply -mfpu=neon

Creates a merge between the master and experimental branches. Fixes a
number of conflicts in the build system to allow *either* VP8 or VP9
to be built. Specifically either:
$ configure --disable-vp9 $ configure --disable-vp8
--disable-unit-tests
VP9 still exports its symbols and files as VP8, so that will be
resolved in the next commit.
Unit tests are broken in VP9, but this isn't a new issue. They are
fixed upstream on origin/experimental as of this writing, but rebasing
this merge proved difficult, so will tackle that in a second merge
commit.

Most of these were picked up by jenkins in the commit that changed
the vp8 namespace to vp9 in common/.

Quickly modified the ssse3 sixtap filters to support eight taps. For the test
clip used, a 23+% boost in decoder performance was seen. We can
revisit later and improve further.

First sse2 version of vp8_mbloop_filter_vertical_edge(). For now,
intrinsics are being used until the bitstream is finalized. This function
will be revisited later for further performance improvements.
For the test clip used, a 34+% decoder performance improvement
was seen. This will vary depending on material.

First sse2 version of vp8_mbloop_filter_horizontal_edge(). For now,
intrinsics are being used until the bitstream is finalized. This function
will be revisited later for further performance improvements.
For the test clip used, a 31+% decoder performance improvement
was seen. This will vary depending on material.

Alternative strategy for finding a list of candidate motion
vectors to use as reference values in mv coding and as
nearest and near.
Sort by sad in vp8_find_best_ref_mvs() rather than just
pick the best. Allow 0,0 as a best ref option but not a
nearest or near unless there are no alternatives.
Encode/Decode verified on at least some clips.
Some commented out experimental and stats code still in place.
Gain over existing code averages about 1% on derf (alll metrics)
with improvement on all clips. Other test results pending.
The entropy coding of the mode (nearest/near etc) still
depends upon and requires the old "findnear" code so
this needs looking at and may provide room for further gains.

About 3.5x faster, 30% overall encoder speedup. Rest of optimizations
will come soon (see TODO section in filter_sse4.c).

Latest version of all scripts/makefile but rtcd_defs.sh is empty, all
existing functions are still selected using the old/current way.

The commit changed how baseline 8x8 coefficient probabilities are
initialized, to be consistent with the initialization of baseline
4x4 coefficient probabilities.
The commit does not have any effect on compression.

Rework unit tests to have a single executable rather than many, which
should avoid pollution of the visual studio project namespace, improve
build times, and make it easier to use the gtest test sharding system
when we get these going on the continuous build cluster.

(see Change I9b2ccc88: Makes all mode token tables const)
Further remove runtime table initialization and use
precalculated const data. Data footprint reduced
by 4112 bytes.

In a previous commit, the duplicate of headerfile defaultcoefcounts.h
was identified. This commit updates the .mk file to ensure configure
and make works properly for all platforms.

Break MFQE code into it's own file.
It is currently only valid for 16x16 and 8x8 Y blocks. It also filters
4x4 U/V blocks.
Refactor filtering and add associated assembly. Limited test cases show
--mfqe introduces a penalty of ~20% with HD content. The assembly
reduces the penalty to ~15%

For the experimental branch we are trying to slim the codebase
down removing features such as threading for now which complicate
the process of development and testing.

This function adds the common prediction modules, some data structures
and a config option but does not use them.
It also corrects a bug in clearing down the MODE_INFO border and introduces
a new element that indicates if an entry corresponds to an "in image" macro block
or is part of the border.
