Fix rdoc.
* ext/objspace/objspace.c (ObjectSpace.count_tdata_objects):
  Change key type if the klass of a object is zero (internal object).
  Read rdoc for details.
* internal.h: export rb_objspace_data_type_name().

* This method is not for ordinary Ruby programmers, but for MRI developers

* The contents of the returned hash is implementation defined.
* It may be changed in future.
*
* In this version, keys are Class object or Symbol object.
* If object is kind of normal (accessible) object, the key is Class object.
* If object is not a kind of normal (internal) object, the key is symbol
* name, registered by rb_data_type_struct.
*
* This method is not expected to work except C Ruby.
