Remove the weston_view.geometry.width/height fields

This has a couple of additional implications for the internal weston API:
 1) weston_view_configure no longer exists.  Use weston_view_set_position
    instead.
 2) The weston_surface.configure callback no longer takes a width and
    height.  If you need these, surface.width/height are set before
    configure is called.  If you need to know when the width/height
    changes, you must track that yourself.
