Move this into it's own file so that folks don't need to include shell.h to
access it.

used system/user/login_status instead, as sadrul suggested.

+    NOT_LOGGED_IN,
+    LOGGED_IN,

[Daniel Erat, 2012/04/18 16:50:42]

It'd probably be clearer to name this LOGGED_IN_AS_USER or something similar. 
Otherwise, someone could see the LOGGED_IN value without being aware of
LOGGED_IN_AS_GUEST and figure that LOGGED_IN covered the guest case as well.

+    LOGGED_IN_AS_GUEST,
+  };

[sadrul, 2012/04/18 16:53:20]

Can you please use ash::user::LoginStatus instead? (in
ash/system/user/login_status.h)

[Jun Mukai, 2012/04/19 06:19:25]

Done.
