Experiment for mid group second arf. This patch implements a mechanism for inserting a second arf at the mid position of arf groups. It is currently disabled by default using the flag multi_arf_enabled. Results are currently down somewhat in initial testing if multi-arf is enabled. Most of the loss is attributable to the fact that code to preserve the previous golden frame (in the arf buffer) in cases where we are coding an overlay frame, is currently disabled in the multi-arf case.
