This commit fixes a bug in denoiser reference frame buffer swap,
which disables frame buffer update.

On Nexus 7 speed -5, -6, -7, and -8 saw about a 1% increase
in perf for 480p. Speeds -5, -6, -7, and -8 saw about a 1.5%
increase in perf for 720p.
Tested on Nexus 7, built with ndk r10d, gcc 4.9.

On some platforms, such as 32bit Windows and 32bit Mac, the allocated
memory isn't aligned automatically. The thread data is aligned to
ensure the correct access in SIMD code.

This commit adds encoder side control for vp9 to set color space info
in the output compressed bitstream.
It also amends the "vp9_encoder_params_get_to_decoder" test to verify
the correct color space information is passed from the encoder end to
decoder end.

Don't put small empty frame in front of a key frame. We will
put key frame flag in webm container if there's a visible key
frame. But there will be decoding error when we seek to here
if we put the small empty frame, which will be inter frame,
in front of it.

Add optimized Neon functions of:
vp9_variance32x64
vp9_variance64x32
vp9_variance64x64
On Nexus 7 speed -5 and -6 saw about a 4% increase in perf.
Speeds -7 and -8 saw about a 6% increase in perf.

Replaced "color space" with "color format" in comments where color
sampling format is concerned, so to differentiate from the concept
defined in COLOR_SPACE.

This commit refactors the motion compensated reference block fetch
process in denoiser. It skips the stage that generates motion
compensated reference block if denoiser decides to use copy block
mode. For high motion clips, this could speed up the denoising
process by about 10%.

Use frame buffer pointer swap instead of memcpy when possible.
These two CLs make the denoiser when running on vidyo1 720p at
speed -6 over 10% faster.

These two parameters are used to control the denoiser cut-off
thresholds. They should be properly initialized when starting
mode search of a given block.

The vp9_denoiser_free() function will internally check if the
buffer pointers are NULL. This commit makes the encoder always
call vp9_denoiser_free() after finishing encoding. It protects the
case where noise_sensitivity_level is changed during encoding
process and happen to be turned off towards the end of sequence,
which could result memory space allocated to denoiser not being
released.

Use the correct frame size and stride value for chroma components
when setting the initial values. These control parameters are
assigned when the denoiser buffer was allocated and initialized.

Allocate the frame buffer allocation for denoiser once during the
encoder initialization. This avoids allocating frame buffer
multiple times and overwriting the buffer pointer without proper
releasing.

When testing frame sse to choose a loop filter value and
when checking ambient error in kf Q selection, use 64 bit
values for accumulating the sse, to avoid risk of overflow
for large image formats.

This makes the inter_mode counts update consistent with other symbols.
Also, forward updates should work corerctly now.

This commit fixes the buffer alignment control in denoised video
output function. The encoder is now able to properly store the
denoised input video into provided file when enabled.

Use mbmi->segment_id directly in vp9_pick_inter_mode. The value is
set outside this function, hence no need to assign it again.

Check if block size is below 8x8 for rectangular block coding. It
is added to support 4x8 and 8x4 block coding for RTC mode.
