I now see I didn't write a very long description, so let's do it here then. We took a pretty big quality hit (0.1-0.2%) from my recent fix of the inversion of arguments to vp8_cost_bit() in the RD reference frame costing. I looked into it and basically the costing prevented us from switching reference frames. This is of course silly, since each frame codes its own prob_intra_coded, so using last frame cost indications as a limiting factor can never be right. Here, I've rewritten that code to estimate costings based partially on statistics from progress on current frame encoding. Overall, this gives us a ~0.2%-0.3% improvement over what we had previously before my argument-inversion-fix, and thus about ~0.4% over current git (on derf-set), and a little more (0.5-1.0%) on HD/STD-HD/YT.
