Change to arf boost calculation. In this commit I have added an experimental function that tests prediction quality either side of a central position to calculate a suggested boost number for an ARF frame. The function is passed an offset from the current position and a number of frames to search forwards and backwards. It returns a forward, backward and compound boost number. The new code can be deactivated using #define NEW_BOOST 0 In its current default state the code searches forwards and backwards from the proposed position of the next alt ref. The the old code used a boost number calculated by scanning forward from the previous GF up to the proposed alt ref frame position. I have also added some code to try and prevent placement of a gf/arf where there is a brief flash. Change-Id: I98af789a5181148659f10dd5dd2ff2d4250cd51c
