Add Event Trace to the intel-pt-events.py script. This shows how to unpack
the raw data from the new sample events in a Python script.

The intel-pt-events.py script displays only the last of consecutive switch
statements but that may not be the last switch event for the CPU. Fix by
keeping a dictionary of last context switch keyed by CPU, and make it
possible to see all switch events by adding option --all-switch-events.

As an example, add branch information to intel-pt-events.py script.
This shows how a simple python script can be used to customize
perf script output for Intel PT branch traces or power event traces.

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.
The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6

Remove mixed indentation in Python scripts. Revert to either all tabs
(most common form) or all spaces (4 or 8) depending on what was the
intent of the original commit. This is necessary to complete Python3
support as it will flag an error if it encounters mixed indentation.
