perf: Add the timechart tool
timechart is a tool to visualize what is going on in the system.
The user makes a trace of what is going on with
> perf record --timechart /usr/bin/some_command
and then can turn the output of this into an svg file
> perf timechart
which then can be viewed with any SVG view; inkscape works well
enough for me.
The idea behind timechart is to create a "infinitely zoomable"
picture; something that has high level information on a 1:1 zoom
level, but which exposes more details every time you zoom into a
specific area.
