remove unused things from object.[ch]

Browse source 
* libguile/objects.h:
* libguile/objects.c (scm_object_procedure): Remove, it was only
  compiled with SCM_DEBUG.

* libguile/objects.h:
* libguile/objects.c (scm_make_class_object, scm_make_subclass_object,
  (scm_i_make_class_object, scm_metaclass_standard): Remove also. These
  implemented an undocumented object system, and are totally replaced by
  GOOPS.
