Fix for SF bug #485678.
slot_tp_descr_set(): When deleting an attribute described by a
descriptor implemented in Python, the descriptor's __del__ method is
called by the slot_tp_descr_set dispatch function. This is bogus --
__del__ already has a different meaning. Renaming this use of __del__
is renamed to __delete__.

Type/class unification and new-style classes
+- The "delete attribute" method of descriptor objects is called
+ __delete__, not __del__. In previous releases, it was mistakenly
+ called __del__, which created an unfortunate overloading condition
+ with finalizers. (The "get attribute" and "set attribute" methods
+ are still called __get__ and __set__, respectively.)
