[Python-3000] Default dict iterator should have been iteritems()

I don't remember the discussion in detail, but a couple of
reasons that come to mind:

* It would be confusing to have "x in d" and "for x in d"
meaning subtly different things.

* It's more efficient to iterate over just the keys,
because a tuple has to be created for each item when
iterating over (key, value) pairs. It's reasonable
that if you want more done, you should have to write
more to get it.
