a220b931f5 vp9: compute skinmap only once before encoding.
This could save some cycles since skin detection is used in multiple
places in vp9.

1~2% speed up on ARM.

1b59964162 vp9: Adjustment to noise estimation.
When the noise estimate is forced off due to large motion,
reset the counter and set smaller window for next estimate.

spatial layer is a key frame. And allow for better/lower
QP on high spatial layers when their base layer is key frame.

9f90473ef8 vp9: Fix condition to update consec_zero_mv.
Fix will reset the consec_zero_mv map on non-skipped blocks with non-zero mv.
Adjust thresholds on consec_zero_mv in noise estimation and skin detection,
as more possible reset on map means lower thresholds should be used.

c7da053d4b Move noise level estimate outside denoiser.
Source noise level estimate is also useful for
setting variance encoder parameters (variance thresholds,
qp-delta, mode selection, etc), so allow it to be used also
if denoising is not on.
