Marco 03e8f13337 vp9: Modification to adapt the ARF usage for 1 pass vbr
Add stats for past ARF usage, and use it to disable
ARF usage based on some conditions.

Overall improvement on ytlive set, reduces the regression
on the problem clips for this feature.

Only affects when sf->use_altref_onepass is enabled
(currently off by default).
