Makes the delta-qp stop little earlier on areas that have been refreshed enough.
This helps to reduce some pulsing artifact on noisy flat areas observed in some
noisy vc-clips.
Threshold changes only take effect for sources where noise level is estimated to
be >= medium level.
Only affects 1 pass CBR, non-screen content case.

Makes the noise estimation react little faster.
Little/no change in metrics.

"qc" in vp{9,10}_token_state is used to save quantized coefficients, this
commit changes the type from short to tran_low_t to properly reflect
the value range for highbitdepth build.
This fixes an out-of-range bug when optimize_b is used in highbitdepth
build.

This is an actual overflow where the result of the calculation is
materially changed, not just a negative value that is stored in an
unsigned.
Caught with fsanitize=integer on the VP9/AqSegmentTest.TestNoMisMatchAQ2/1 test.

In so doing this fixes a couple of bugs:
vpx_plane_add_noise.c needed to subtract a clamp instead of add.
And the assembly (mmx sse) had assumptions that parameters were
continuous in memory which was not true.

- iOS SDKs no longer ship with armv6 support.
- Our minimum iOS version means all target devices have neon.
- Remove armv6 darwin LD workaround.
- This removes a TODO.

Move skin superblock force split out of this function as well
as some minor code refactors. Checked bitexact for different speed
settings and different resolutions.

this avoids the decoder test which was only correct for vp9, vp10 was
missed in the earlier change

First, we only set use_4x4_partition for key frame where we don't
denoise; second, envision we have small partitions, we should pass the
actual block size to denoiser and make an early termination if needed.

Wrap around behavior is enforced manually and we use the values in
arithmetic involving negative integers.

The product always fits in uint32_t, but the operands don't.
An optimizing compiler should generate the wraparound code.
(Verified with clang).

ADL will look this up from the callsite namespace iff it is declared
before the callsite or from the parent namespace of the class type (the
global namespace).
This patch has been tested on MSVS 2015 and clang-3.8.
