Use scm_gc_malloc ()' when allocating GOOPS t_extension' objects.

Browse source 
* libguile/goops.c (extension_gc_hint): New.
  (scm_c_extend_primitive_generic): Use `scm_gc_malloc ()' instead of
  `scm_malloc ()'.
  (setup_extended_primitive_generics): Don't call `free(3)' when
  removing a `t_extension' object.
