    daemon: Add an interface for communicating with GDM via D-Bus · e0a3c565
    Ray Strode authored
    One goal for GNOME 3.6, is to replace the screen locking functionality
    provided by gnome-screensaver with redesigned functionality provided
    by gnome-shell.
    
    At the same time, it makes sense to consolidate the yucky PAM
    authentication code to one place (GDM).
    
    Right now only greeters can talk to GDM.  At the time the greeter is
    started, the slave sets up a private communication channel which the
    greeter then connects to for initiating communication.
    
    This commit adds a new method to the org.gnome.DisplayManager.Manager
    interface that allows opening a private connection to the slave that
    is associated with the currently running session.  That slave exports
    the session object over the bus that greeters can interact with the
    session as appropriate.  This interface replaces the
    GDM_GREETER_DBUS_ADDRESS environment variable that used to to be used
    for connecting the greeter to the slave.
    
    This commit also drops gdm-greeter-server and gdm-chooser-server which
    don't fit the new model, and are really just thin middle men that don't do
    anything important.
    
    Furthermore, this commit splits GdmSession interfaces 3 orthogonal parts
    up into 3 separate interfaces on the session object.
    
    A future commit will make this interface work for screensavers/reauthentication.
