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.
