Use crop region for global motion estimation

Avoid using the pixels which were added to make y_width/y_height be
multiples of 8 pixels. These extra pixels are not part of the visible
image, so we should not consider them.

Also fix rounding during calculation of segment_map_{w,h}. The previous
code allocated one element too many along each axis if the frame width
or height was a multiple of 32 pixels.
