This way the shell can know when a surface has been unmapped by checking the value returned by weston_surface_is_mapped(surface). The configure handlers have now width and height parameters, so they do not need anymore to check manually the buffer size. If a surface's buffer is NULL the width and height passed to the configure are both 0. Configure is now only called after an attach. The variable weston_surface.pending.newly_attached is set to 1 on attach, and after the configure call is reset to 0.
