xdg-shell: Document the set_maximized and unsetmaximized requests
xdg-shell: Document the set_maximized and unsetmaximized requests

This patch changes the semantics (compared to the previous version of
this patch) of maximizing/unmaximizing an already maximized/unmaximized
surface to always result in a configure event. Doing it this way would
be more consistent with how the compositor works regarding other
configure events i.e. send many, letting the client ignore when needed
(for example during resize).
