[PATCH v2] xdg-shell: Add tiled state

[Olivier Fourdan]

When tiled, clients must obey the window geometry specified in the
configure event and can choose to hide some of their decorations.

 v2: Simplify the proposal and keep only one "tiled" state instead of one
     per edge.

     Note that the edges in my initial proposal were surface edges, not
     monitor edges. Anythow, if some other (tiling) Wayland compositor
     needs more granularity, we could use the "draw states" from Mike's
     proposal.

     I do however reckon that "tiled" is not the same as "maximized",
     even though a client has to obey the geometry in both cases, a
     client would need to distinguish between the  two states to adapt
     its decorations accordingly.

     A single "tiled" state would get my vote (at least ^_~) as it's
     simple enough.
