tweak raise/dict syntax for Python 3 compat

Use the `raise` statement directly.

Switch to using .items() instead of .iteritems().  Python 3 doesn't
have .iteritems() as .items() is a generator, and these are small
enough that the Python 2 overhead should be negligible.

We have to run .keys() through list() in a few places as Python 3
uses a generator and we sometimes want to iterate more than once.
That's why we don't change all .keys() or .items() calls -- most
are in places where generators are fine.
