Subject: [PATCH] Client: expose toplevel window state
QWaylandWindow has only basic information about window state, like if
it's active or maximized, but it has no information about tiling, which
can be useful for client-side decorations. We also need to bump version
of xdg-shell protocol we support, because additional states are not in
the version currently supported by QtWayland. It shouldn't be a problem
to increase the version as the new version adds just these additional
window states.
