Renamed PyObject_GenericGetIter to PyObject_SelfIter
...
to more accurately describe what the function does.

Remove the next() method -- one is supplied automatically by
...
PyType_Ready() because the tp_iternext slot is set (fortunately,
because using the tp_iternext implementation for the the next()
implementation is buggy). Also changed the allocation order in
enum_next() so that the underlying iterator is only moved ahead when
we have successfully allocated the result tuple and index.

- New builtin function enumerate(x), from PEP 279. Example:
...
enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c").
The argument can be an arbitrary iterable object.
