    Adaptive motion control on ref and search range

    This commit takes a preliminary attempt to refine the motion search
    control. It detects the SAD associated with mv predictor per reference
    frame, and based on which to determine whether the encoder wants to
    reduce the motion search range (if the predicted mv provides fairly
    small SAD), or to skip the current reference frame (if there exists
    another ref frame that gives much smaller SAD cost).
