Arjan van de Ven 5094b65545 perf util: Make the timechart SVG width dynamic
This patch adds a command line option for timechart that allows the
user to specify the width of the SVG file.

This patch also makes sure that each second of recording has at
least 200 units (pixels at 96 DPI) of width.  This impacts
recordings longer than 5 seconds; recordings shorter than 5 second
will scale up to have a width of 1000 units for the whole recording
(as before).

Arjan van de Ven a92fe7b306 perf timechart: Show the duration of scheduler delays in the SVG
Given that scheduler latencies are the hot thing nowadays, show the
duration of said latencies in the SVG in text form.

In addition, if the latency is more than 10 msec, pick a brighter
yellow color as a way to point these long delays out.

Arjan van de Ven 4f1202c8e6 perf timechart: Show the name of the waker/wakee in timechart
Timechart currently shows thin green lines for sending or receiving
wakeups. This patch also prints (in a very small font) the name of
the process that is being woken/wakes up this process.

Arjan van de Ven f48d55ce78 perf: Add a SVG helper library file
The timechart tool writes out SVG format output; this patch adds a
set of helper functions to abstract dealing with SVG from the core
timechart code.
