Adds a new interpolation experiment. Improves entropy coding to send the filter type only if the motion vectors have subpel components. Adds one new 8-tap smooth filter, and tweaks the others. derflr: +0.695% hevcmr: +0.305% About 5% encode slowdown. No visible impact for decoding. Also makes the interpolation framework flexible to support both strictly interpolating filters as well as non-interpolating filters that filter integer offsets. This is mainly for further experimentation and if not found useful the code will be removed. Change-Id: I8db9cde56ca916be771fe54a130d608bf10786e6
