Fix warnings

2007-12-05  Alexander Larsson  <alexl@redhat.com>

        * gdatainputstream.c:
	Fix warnings
	
        * gio.symbols:
        * giomodule.[ch]
        * glocaldirectorymonitor.c:
        * glocalfilemonitor.c:
        * gunionvolumemonitor.c:
        * gvfs.c:
	Make g_io_modules_ensure_loaded a private function and
	don't pass in the dirname. This means we can do magic
	directory finding in the win32 version.
	Export the actual load-modules-in-directory code so that
	gvfs can reuse that.
