[gdm/wip/xserver-in-session: 41/54] session: add authentication-failed signal

[Ray Strode <halfline src gnome org>]

    session: add authentication-failed signal
    
    This signal records when a user tried to log in but typed
    the wrong password (or whatever).
    
    We'll need this to move session recording up to GdmManager.
