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.

Support both Python2 and Python3 in the failed-syscalls-by-pid.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

This provides valuable information for tracing performance problems.
Since this change alters the interface for the python scripts, also
adjust the script generation and the provided scripts.

Older kernels (e.g., RHEL6) do system call tracing via the
syscalls:sys_{enter,exit} tracepoints rather than using raw_syscalls:*.
Update perf python and perl scripts to fallback to syscalls:* when
raw_syscalls:* isn't available.

The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.
This problem was introduced in 133dc4c.

Adds a set of scripts that aggregate system call totals and system
call errors. Most are Python scripts that also test basic
functionality of the new Python engine, but there's also one Perl
script added for comparison and for reference in some new
Documentation contained in a later patch.
