[systemd-devel] [RFC][PATCH v2] analyze: draw kernel and initrd boot time as well

Sample output without initrd: http://dominion.thruhere.net/koen/angstrom/systemd/omap4430-panda-201109221422.svg

Second attempt at this, please check the logic in this patch, a quick test on F15 looks OK, but I'd like more datapoints from initrd users.

Changes since v1:
	* add initrd bar, tested on a F15 install
