Modify reference frame segmentation so that ONE or MORE reference frames may be marked as a available for a given segment. Fixed bugs relating to segment coding of INTRA and some INTER modes at the segment level. Modified Q boost for static areas based on ambient average Q. Strong results now on clips with significant static areas. (some data points in derf set as high as 9% and some static & slide show type content in YT set > 20%) Change-Id: Ia79f912efa84b977f35a23683ae3643251e24f0c
