In preparation for the transition to Python 3, convert to using the
print function. The special import
from __future__ import print_function
in Python 2.7 makes "print" become the function and not the statement.
In Python 3, it has no effect. Once the transition is done and we
exclusively use Python 3, we can simply remove the imports.
The testsuite shows no regressions.
