Log Message:
"Fix" for SF bug #520644: __slots__ are not pickled.

As promised in my response to the bug report, I'm not really fixing
it; in fact, one could argule over what the proper fix should do.
Instead, I'm adding a little magic that raises TypeError if you try to
pickle an instance of a class that has __slots__ but doesn't define or
override __getstate__.  This is done by adding a bozo __getstate__
that always raises TypeError.

Bugfix candidate (also the checkin to typeobject.c, of course).

  Core and builtins
  
+ - If you try to pickle an instance of a class that has __slots__ but
+   doesn't define or override __getstate__, a TypeError is now raised.
+   This is done by adding a bozo __getstate__ to the class that always
+   raises TypeError.  (Before, this would appear to be pickled, but the
+   state of the slots would be lost.)
+ 
  - PyErr_Display will provide file and line information for all exceptions
    that have an attribute print_file_and_line, not just SyntaxErrors.
