sharpness was not recalculated in vp8cx_pick_filter_level_fast remove last_filter_type. all values are calculated, don't need to update the lfi data when it changes. always use cm->sharpness_level. the extra indirection was annoying. don't track last frame_type or sharpness_level manually. frame type only matters for motion search and sharpness_level is taken care of in frame_init move function declarations to their proper header Change-Id: I7ef037bd4bf8cf5e37d2d36bd03b5e22a2ad91db
