Change event name generate script to be python 2/3 compatible

Python 3 doesn't have a print statement, only a print function.

Fixed with:
  2to3 make-event-names.py | git apply

Print as function requires Python 2.6 which is reasonable enough given
that even RHEL6 ships that.

Even though it's not needed for 2.6, use
	from __future__ import print_function
to avoid accidentally introducing a print statement in the future.
With this line, print "blah" is now a syntax error in python 2.
This line was added manually, after the 2to3 conversion.
