splitting the existing code between a frontend script that parses arguments
and does taint checking, and a backend library where all the work is done
(including permission checks). The interface to the libraries is simple
right now (didn't want to spend a lot of time on designing interface
without knowing if the approach would work long term).

	use libreboot;
	use libosload;

        nodereboot(\%reboot_args, \%reboot_results);
        osload(\%reload_args, \%reload_results);

Arguments are passed to the libraries in the form of a hash. For example,
in os_setup:

	$reload_args{'debug'}     = $dbg;
	$reload_args{'asyncmode'} = 1;
	$reload_args{'imageid'}   = $imageid;
	$reload_args{'nodelist'}  = [ @nodelist ];

Results are passed back both as a return code (-1 means total failure right
away, while a positive argument indicates the number of nodes that failed),
and in the results hash which gives the status for each individual node. At
