In Python 2, map() returns a list; in Python 3 it returns an iterator.
Replace all uses by list comprehensions, generators, or for loops,
as required.

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.

Drop support for pylint < 1.0
Enable ignoring unknown attributes on modules (both nose and pytest
use advanced techniques, support for which only made it to pylint
recently)
Fix some bugs revealed by pylint
Do minor refactoring or add pylint:disable directives where the
linter complains.
