d1e3d0467c VPX skin map improvement. 
Use multiple clusters instead of one and decrease
the distance thresholds.

Add a define to switch between models.
Default is set to existing (1 cluster) model.

b39a599cef vp9 non-rd mode: Modification for detected skin areas. 
If a superblock contains alot of "skin" then force split
of 64x64 partition, and make some adjustments in mode selection.

This helps to reduce artifacts on moving face/skin areas at low bitrates.

Little/no change in metrics: avgPSNR/SSIM down by ~0.12%.
Small encoding time increase < 1%.

fab630fac9 vp9-aqmode=3: Limit on period for golden update. 
For aqmode=3, golden period update is set based on period of cyclic refresh.
Put a limit on max golden period update, for now set to 40.
And fix comment.

4b2b90fed3 vp9: Be more responsive to massive overshoot. 
Limit oscilation detection in the case where overshoot is very very
large.

This keeps the 9-bit cost patch from breaking the DownUp reisze test.
The patch pushed us to an 11% undershoot right before a scene cut
causing a 1200% overshoot. (Whereas before we were undershooting by
only 6% before overshooting by 1200%).

733bbab53a Loop filter search resets on overlay frame. 
This patch fixes a bug that causes the loop filter search to reset to
a low value or zero after each arf overlay frame. We expect the overlay
frames to need little or no loop filtering but this should not propagate.
