Lock amd and symbfact to avoid segmentation fault with SuiteSparse (bug #57435). * dldfcn/amd.cc (Famd), dldfcn/symbfact.cc (Fsymbfact): Use DEFMETHOD_DLD. Call "mlock" to avoid having invalid function pointers in global SuiteSparse_config structure when the functions are unloaded (e.g. with "clear functions").
