Summary: Tuple iterator type

Initial Comment:
Created a tuple iterator type modelled after the 
dictionary iterator type.  Added the new type to the 
tp_iter slot of tuple.

Optimizes list conversion and looping access by 19% 
over the current method of tapping the sq_item slot 
with an iterobject.

External interface unchanged.  No doc changes needed.  
Tests okay with Lib/tests/test_builtin.py.

Done.  Added GC to tp_flags, tupleiter_new(), and 
tupleiter_dealloc().  Copied from iterobject.c ver 1.8.  
Please double check -- my understanding of GC is shallow.

I think this object needs to participate in GC.
