This patch creates a per-output paint node list in the same z-order as
the global view_list in weston_compositor.
The next step is to switch output repaints and backends to use the
z-order list instead of view_list.
Having a per-output paint node list for repaints allows including only
those paint nodes that actually contribute to the output image, so that
completely occluded and out-of-screen views can be ignored in libweston
core already.
