Ignore -Woverride-init in event-names.h

Having the declarations in the form of [0...EV_MAX] = NULL together

-Woverride-init is enabled.

We can drop them for most as they're zero, but still need them for
ev_max (which defaults to -1), not zero. So use the GCC pragma to

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.
