only uint8 is required; each use only loads one value as a uint8
quiets a few type conversion warnings

There is a naming conflict in the chromium build system.
The rest of the variance functions will move to vpx_dsp soon.

the tests were recently enabled in:
eb88b17 Make vp9 subpixel match vp8
the functions likely haven't changed since being converted from assembly

Clang adds alignment hints when casting up the loads/stores. Although
this should be safe for most paths, it's causing some crashes. Either
the source of the misalignment needs to be determined and adjusted or
the intrinsics need to be rewritten to avoid using the cast to load the
data.

Numerator was being range checked against the
denominator - preventing any frame rate slower
than 1 fps.
I've tested this on a Mac using using ffmpeg and
results are comparable to mp4 and ogg files generated
at the same time.
Not yet tested on Windows.

This allows rate control to react to content of current frame being encoded.
Enabling this feature via the setting: screen_content_mode = 2.

this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

Create a new component, vpx_dsp, for code that can be shared
between codecs. Move the SAD code into the component.
This reduces the size of vpxenc/dec by 36k on x86_64 builds.

While CONFIG_INTERNAL_STATS=1, PSNR is calculated while encoding.
The aligned width/height were used mistakenly in the calculation.
This patch fixed it, and used the orignal image width/height.

In vp8_sub_pixel_variance8x8_neon the temp2 buffer is only initialized
to kHeight8 * kWidth8. However, in the case that xoffset != 0 and
yoffset == 0, var_filter_block2d_bil_w8 is called with output_width
kHeight8PlusOne.
Thanks to cmugurel for diagnosing and yulius for the patch.

By using 0xff for a short it was not setting the high bits. When
comparing the output with vtst to find non-zero elements it was skipping
vaules which had no low bits set such as -512 / 0xFE00.
Using -8191 as the first element of coeff will generate this condition.
