Make the step engine more powerful and add a soft-reboot test that uses it

This patch abstracts out the state maintained for the step engine.  This allows  control files and autotest itself can save variables between reboots.  This will allow testing that involves reboots to be much more robust and will allow it to still play nicely with the autotest web frontend.  Attached is a soft-reboot test that takes advantage of this functionality.
