Hongbin Lu 0b9b7de79a Eliminate mutable default arguments

The best practice in Python is not to use mutable object (i.e. list,
dictionary, or instances of most classes) as value of default argument.

See: https://docs.python.org/2/tutorial/controlflow.html#default-argument-values

This patch also added a hacking rule to enforce this practice.
