Use segmented error metric for global motion

This computes the error metric over blocks that contain inliers
from the motion model. If an insufficient number of blocks contain
inliers, the old error metric is used.

This currently gives 0.15% BDRATE gain and 1% speedup on
cam_lowres, speed 2. Parameters still need to be tuned for
speed 1 and 0.
