compositor, clients: double-buffer input region

Browse Source 
Make input region double-buffered as specified in the new protocol.

While doing it, get rid of the undef region code, and instead use a
maximum sized real pixman region. This avoids special-casing regions
that might sometimes be undef.

As the input region is now usable by default instead of undef,
weston_surface_update_transform() does not need to reset the input
region anymore.

weston_surface_attach() no longer resets the input region on surface
size change. Therefore, also weston_seat_update_drag_surface() does not
need to reset it.

Update toytoolkit to set input region before calling wl_surface_commit()
or swapBuffers (which does commit).
