This CL fixes an overcite with the AVX2 support CL previously
merged (Change-Id: Idc03f3fca4bf2d0afd33631ea1d3caf8fc34ec29) that
prevented runtime execution of AVX2 code in WebM. 

Background:
Starting with the Sandybridge processor, the CPUID instruction was
enhanced to add various extended feature flag enumeration leaves.
Reading these leaves requires an additional input value for the CPUID
instruction which is stored in ECX. This change adds this second input
value for all ARCH_X86 and ARCH_x86_64 targets to the CPUID macros,
allowing checks of EBX bit 5 for AVX2 support. This capability will be
required moving forward to check for future processor features.

Disable unit-tests. The logging in GTest would need to be adjusted.

Restructure ARM cpu detection. Flatten if-else logic.

Change #if defined(HAVE_*) to #if HAVE_* because we only need to check
for features that the library was actually built with. This should have
been harmless, as disabled feature sets wouldn't have any features to
call.

Soft enable runtime cpu detect for armv7-android target, so that it
can be disabled and remove dependency on 'cpufeatures' lib.
Change the arm_cpu_caps implementation selection such that 'no rtcd' takes
precedence over system type.

Switch to use -mtune instead of -mcpu. NDK was complaining about
-mcpu=cortex-a8 conflicting with -march=armv7-a, not sure why.

Add a linker flag to fix some cortex-a8 bug, as suggested by NDK Dev
Guide.

Examples:
Configure for armv7+neon:

./configure --target=armv7-android-gcc \
            --sdk-path=/path/to/android/ndk \
            --disable-runtime-cpu-detect \
            --enable-realtime-only \
            --disable-unit-tests

...armv7 w/o neon:

./configure --target=armv7-android-gcc \
            --sdk-path=/path/to/android/ndk \
            --disable-runtime-cpu-detect \

Allows building the library with the gcc -pedantic option, for improved
portabilty. In particular, this commit removes usage of C99/C++ style
single-line comments and dynamic struct initializers. This is a
continuation of the work done in commit 97b766a4, which removed most
of these warnings for decode only builds.

This change is to allow obj_int_extract to extract all integers
in the data segment. With the const keyword these variables are
forced into the .rodata segment even for zero variable value.

We had a problem before that zero valueed variables would get
assigned to BSS segment that fooled obj_int_extract to give
incorrect values.

Add PRIVATE macro for adding private_extern directive for yasm
to hide global symbols. This is only enabled if -DCHROMIUM is used

Also fixed a small problem with	rtcd_defs.sh to guard TEMPORAL_DENOISING.

Original patch by Ginn Chen <ginn.chen@oracle.com> against libvpx
 v0.9.0.
I've forward-ported it to the current version (which mostly
 involved removing hunks that were no longer relevant), since I've
 given up on getting Ginn to submit this upstream himself.

This is a code snapshot of experimental work currently ongoing for a
next-generation codec.

The codebase has been cut down considerably from the libvpx baseline.
For example, we are currently only supporting VBR 2-pass rate control
and have removed most of the code relating to coding speed, threading,
error resilience, partitions and various other features.  This is in
part to make the codebase easier to work on and experiment with, but
also because we want to have an open discussion about how the bitstream
will be structured and partitioned and not have that conversation
constrained by past work.

Our basic working pattern has been to initially encapsulate experiments
using configure options linked to #IF CONFIG_XXX statements in the
code. Once experiments have matured and we are reasonably happy that
they give benefit and can be merged without breaking other experiments,
we remove the conditional compile statements and merge them in.

Current changes include:
* Temporal coding experiment for segments (though still only 4 max, it
  will likely be increased).
* Segment feature experiment - to allow various bits of information to
  be coded at the segment level. Features tested so far include mode
  and reference frame information, limiting end of block offset and
  transform size, alongside Q and loop filter parameters, but this set
  is very fluid.
* Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used
  in MBs using 16x16 prediction modes within inter frames.
* Compound prediction (combination of signals from existing predictors
  to create a new predictor).
* 8 tap interpolation filters and 1/8th pel motion vectors.
* Loop filter modifications.
* Various entropy modifications and changes to how entropy contexts and
  updates are handled.
* Extended quantizer range matched to transform precision improvements.

There are also ongoing further experiments that we hope to merge in the
near future: For example, coding of motion and other aspects of the
prediction signal to better support larger image formats, use of larger
block sizes (e.g. 32x32 and up) and lossless non-transform based coding
options (especially for key frames). It is our hope that we will be
able to make regular updates and we will warmly welcome community
contributions.

Please be warned that, at this stage, the codebase is currently slower
than VP8 stable branch as most new code has not been optimized, and
even the 'C' has been deliberately written to be simple and obvious,
not fast.

The following graphs have the initial test results, numbers in the
tables measure the compression improvement in terms of percentage. The
build has  the following optional experiments configured:
--enable-experimental --enable-enhanced_interp --enable-uvintra
--enable-high_precision_mv --enable-sixteenth_subpel_uv
