Log:
2008-04-16  Matthias Clasen  <mclasen redhat com>

        Avoid possible memory corruption in xdgmime, fd.o bug 12512,
        reported by Joe Shaw and Federico Mena Quintero.

        * xdgmime.c(_xdg_mime_media_type_equal): Implement.
        (xdg_mime_media_type_equal): Turn into a wrapper around the
        _-prefixed version.

        * xdgmimecache.c: Use the _-prefixed versions of
        comparison functions throughout.
