Kernel+Userland: Addd reboot syscall (#334)
Rolling with the theme of adding a dialog to shutdown the machine, it is probably nice to have a way to reboot the machine without performing a full system powerdown. A reboot program has been added to `/bin/` as well as a corresponding `syscall` (SC_reboot). This syscall works by attempting to pulse the 8042 keyboard controller. Note that this is NOT supported on new machines, and should only be a fallback until we have proper ACPI support. The implementation causes a triple fault in QEMU, which then restarts the system. The filesystems are locked and synchronized before this occurs, so there shouldn't be any corruption etctera.
