removes the need for an intermediate cast to int, which was missing in
the call added in:
69c5ba1 vpx_mem: Refactor code
quiets a visual studio warning:
C4146: unary minus operator applied to unsigned type, result still
unsigned

This patch is to address concerns that changes to allow
recodes on the first frame in each ARF group do not give a
good enough speed quality trade off for speed 2. Though the
average impact on encode speed is 1-2%, for some hard clips
it is > 5% rise. For speed 1 this is less an issue and for Speed 0
the previous patch actually improves speed.

Current commit is just an API template for the rest of the code, and
I will add inner logic later.
Altref frames generate a lot of bitrate and at the same time
other frames refer to them a lot, so it makes sense to apply
special compensation-based adaptive quantization scheme for altref
frames. E.g., for blocks that are good predictors for the future
apply rate-control chosen quantizer while for bad predictors apply
worse one.

Previously Tx domain rd was used in all cases above speed 0.
Coefficient optimization was only enabled for best and speed 0.
This patch selectively sets these features at other speed settings
based on block complexity.
For the Netflix and HD sets in particular the quality gains are
large compared to the speed hit. At speed 1 the average psnr
gain in the NF set is > 2.5% with one clip coming in at 18%
and some points almost 30%. Average gains for the lower
resolution test sets are around 1%.
The gains are biggest at low Q so some further optimization
may be possible.

fixes SSE2/AddNoiseTest.CheckCvsAssembly/0 with -funsigned-char.
visibly broken since:
0dc69c7 postproc : fix function parameters for noise functions.
where the types diverged (char vs. int8)
but likely the return changed in:
2ca24b0 postproc - move filling of noise buffer to vpx_dsp.
when multiple implementations were merged.

set a max allocable size to prevent overflows in 32-bit and extremely
large allocation attempts in 64-bit. this could be amended to allow size
or num parameters to be 64-bits with the correct size being used at each
call site.

vpx_realloc was allocating 1 byte more than needed every time.
Fixed this, and took this opportunity to do a small refactoring.

(cherry picked from aom: 2a876b4 aom_realloc correction.)
In the future this option will activate adaptive quantization special
for altref frames. Encoder will create the adaptive quantization map
on the basis of lookahead buffers similarity which is the estimate of
the future motion compensation performance.

This function only exists as a shortcut to subpixel variance with
predefined offsets. xoffset = 4 for horizontal, yoffset = 4 for vertical
and both for "hv"
Removing this allows the existing optimizations for the variance
functions to be called. Instead of having only sse2 optimizations, this
gives sse2, ssse3, msa and neon.

decoding the same invalid keyframe twice would result in a crash as the
second time through the decoder would be assumed to have been
initialized as there was no resolution change. in this case the
resolution was itself invalid (0x6), but vp8_peek_si() was only failing
in the case of 0x0.
invalid-vp80-00-comprehensive-018.ivf.2kf_0x6.ivf tests this case by
duplicating the first keyframe and additionally adds a valid one to
ensure decoding can resume without error.

Disabled the split mode while encoding 4k video to speed
up the encoder.
Borg test result on 4k set:
Overall PSNR: +0.029%; SSIM: +0.009%.
Average encoder speedup at speed 2 is 2.5%.
Change-Id: I1519c658f07c3ac838affbe5aff0ed9b94f3f8f4
Adjusted speed 2 features to speed up 4k video encoding.
BDBR results from borg test:
PSNR: +0.313%; SSIM: +0.268%.
Average speedup: 8.5%
