Well I found some time today and put this together:
http://gitweb.freedesktop.org/?p=ConsoleKit.git;a=commit;h=eb9361c9b0b05c3bd51de7325c3327db79431fc9

I decided to use the name GetSystemIdleHint because I think perhaps
the name GetAllSessionsIdleHint is a little unclear when there are no
sessions.  I'm not married to the name though.
