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.

The setUp/dearDown names are used in the unittest module, but there is no reason
to use them in non-`unittest` test cases.
Nose supports both styles (but mixing them can cause trouble when
calling super()'s methods).
Pytest only supports the new ones.
