Py3 does not support iter* methods, this commit replaces 2 occurencies
of iteritems() to items(). The dictionaries there are not big, this is
sufficient we do not need to use six.

Metaclass specification is incompatible between Python 2 and 3. Use the
six.with_metaclass helper to specify metaclasses.

The three-argument raise is going away in Python 3. Use the six.reraise
helper instead.

In Python 3, next() for iterators is a function rather than method.

Python 2 has keys()/values()/items(), which return lists,
iterkeys()/itervalues()/iteritems(), which return iterators,
and viewkeys()/viewvalues()/viewitems() which return views.
Python 3 has only keys()/values()/items(), which return views.
To get iterators, one can use iter() or a for loop/comprehension;
for lists there's the list() constructor.
When iterating through the entire dict, without modifying the dict,
the difference between Python 2's items() and iteritems() is
negligible, especially on small dicts (the main overhead is
extra memory, not CPU time). In the interest of simpler code,
this patch changes many instances of iteritems() to items(),
iterkeys() to keys() etc.
In other cases, helpers like six.itervalues are used.
