Check whether the newly focused view is the same as the one currently
fullscreen on that output, or override redirect and don't unfullscreen
in these cases.
The output fullscreen surfaces are drawn in front of everything, without
consideration for view z-order.
If a view is brought to front, unset any fullscreen view that would
cover this view to make sure the view is visible.
The motivation for this is:
- `get_popup` and `get_toplevel` allocate role-specific resources.
- On the first non-null commit, the surface gets mapped.
- On a null commit, the surface gets unmapped. It can be mapped
again with a non-null commit.
- When the role object (xdg-toplevel or xdg-popup) is
destroyed, the surface is unmapped and role-specific resources
are destroyed. The client can call `get_popup` or `get_toplevel`
again on that surface.
- When the xdg-surface object is destroyed, the surface is
unmapped, role-specific resources are destroyed and the surface
itself is destroyed.
