Merge the Isilon ATF code

This is a placeholder merge request to go over all of the items to ensure that I understand everything, some of the items from Isilon can be dropped as I dropped them from the atf branch (diff reduction), and make sure that any valid fixes from NetBSD can be pushed back.
It was replaced with this line:

<pre>
        { "%ld %30s %#llx %-10.*e", "This number %lu%% and string %s has %qd numbers and %.*g floats", 1 },
</pre>
