Log Message:
SF bug #730296: Unexpected Changes in list Iterator

Reverted a Py2.3b1 change to iterator in subclasses of list and tuple.
They had been changed to use __getitem__ whenever it had been overriden
in the subclass.

This caused some usabilty and performance problems.  Also, it was
inconsistent with the rest of python where many container methods
access the underlying object directly without first checking for
an overridden getter.  Users needing a change in iterator behavior
should override it directly.
