        docs/C/gdm.xml: Enable XDMCP configuration so it works.  Previously
        only xdmcp/Enable was being used in the code.  Also add support for
        chooser/Multicast and chooser/MulticastAddr configuration options.
        Now set the default values of MAX_DISPLAY_PER_HOST to 1 and MAX_WAIT to
        30 as specified in the docs.  Add a gdm_settings_direct_get_uint
        function to get unsigned integer configuration values more cleanly
        without the need to cast.  Fixes bug #569876.
