Pass the proper objects to the validation functions from config.py

The problem was that the same validation functions were used both manually,
with a custom option dictionary, as well as used for optparse.TYPE_CHECKER
configuration, where they were expected to receive an optparse.Option object
instead. A common function was created instead, which expects already the choices.
