        Patch from Timo Hoenig <thoenig@suse.de>.

        * bus/bus.c: I've recently investigated why the automatic reload
        of configuration files does not work as expected.

        Currently, reloading configuration files does only work when
        running dbus-daemon with --nodaemon.  If we are running as daemon
        we're hitting a dnotify bug once we fork the process.

        We're initializing the dnotify fds before calling fork().  Once
        the child process forked it does still have the fds (and they
        still show up in /proc/`pidof dbus-daemon`/fd/) but we're not
        getting SIGIO as changes are made to the configuration files.

        The attached patch moves the initialization of the dnotify fds to
        process_config_postinit().  This is safe for all current code
        paths and solves the dnotify disfunction.  If we're running
        dbus-daemon as daemon the fds for dnotify are now being
        initialized after fork() for the child process.

        * configure.in: The current configure.in check for dnotify probes
        'x$target_os' for being 'xlinux-gnu'.  I've changed the check to
        match for 'xlinux', too. Additionally I have adapted the configure
        option's style to match with the others.
