[Sorry the cover letter is after the patch, but I couldn't work out
how to attach something to a cover letter in git send-email.]
This commit adds a program that measures the appliance boot process,
trying to determine which bits take longest. It produces output
similar to that attached.
This patch is not quite finished yet, but I think it demonstrates a
few points already, those points being that SeaBIOS is really slow and
qemu has a lot of overhead.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
