perf script python: add Python3 support to check-perf-trace.py

Support both Python 2 and Python 3 in the check-perf-trace.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 version of
Python2 is now v2.6

(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.

perf scripts python: Give field dict to unhandled callback

trace_unhandled() callback does not allow to access event fields, this patch
resolves the problem.

It can also been used as a more pythonic and flexible way for script writters

This will for example greatly simplify pytimechart event demux.

call errors. Most are Python scripts that also test basic

script added for comparison and for reference in some new
Documentation contained in a later patch.
