perf script: Add stackcollapse.py script
Add stackcollapse.py script as an example of parsing call chains, and
also of using optparse to access command line options.
The flame graph tools include a set of scripts that parse output from
various tools (including "perf script"), remove the offsets in the
function and collapse each stack to a single line. The website also
says "perf report could have a report style [...] that output folded
stacks directly, obviating the need for stackcollapse-perf.pl", so here
it is.
This script is a Python rewrite of stackcollapse-perf.pl, using the perf
scripting interface to access the perf data directly from Python.
