    gio: Add newer dbus UnknownXxxx and PropertyReadOnly errors
    
    Add G_DBUS_ERROR codes for:
    
     * org.freedesktop.DBus.Error.UnknownObject
     * org.freedesktop.DBus.Error.UnknownInterface
     * org.freedesktop.DBus.Error.UnknownProperty
     * org.freedesktop.DBus.Error.PropertyReadOnly
    
    These were discussed on the dbus mailing list
