Clean-ups on switchable interpolation and mv_ref Adds backward adaptation and differential forward updates of switchable interpolation filter probabilities. Also adds some cosmetic cleanups and minor fixes on mv_ref probabilities. derfraw300: +0.353% (with most coming from switchable interp changes) Change-Id: Ie2718be73528c945fd0d80cfd63ca2d9cb3032de
