[PATCH] Introduce set_size_hints xdg_surface request.

[Jari Vetoniemi]

Rationale for this patch is to provide way for applications that can't go below/above
certain bounds to inform compositor about it.

More feedback is needed. For example are maximimum size useful for any
particular application?
