FreeNAS Code

1. Add autotuning support to /boot/loader.conf to override defaults. If you autotune things and the settings differ in /boot/loader.conf, the system will reboot by design to pick up the new settings.
2. Move user tunables (all the ones that can be set via the GUI -- including the screensaver, serial console, etc) to /boot/loader.conf.local so they'll be picked up by FreeBSD on the next boot (see loader_conf_files in /boot/defaults/loader.conf if you're curious).

Note that ix-loader should be run last.

Add ability to force plugin(s) to stop.
