Subject: [PATCH 06/15] perf script python: add Python3 support to intel-pt-events.py
Support both Python2 and Python3 in the intel-pt-events.py script
There may be differences in the ordering of output lines due to
differences in dictionary ordering etc. However the format within lines
should be unchanged.
Fix space/tab inconsistency as python3 enforces consistency.
The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
