[PATCH 5/7] xdg-shell: Implement state set functions.

[antognolli at gmail.com]

From: Rafael Antognolli <rafael.antognolli at intel.com>

The maximized and fullscreen state flags were added, but used only by
the original shell_surface_set_maximized and
shell_surface_set_fullscreen functions, keeping the previous behavior,
removing any other flag that is not the requested one.

Now new functions were added that will only set that specific flag,
allowing both states to be used at the same time.
