I must disagree here. libzfs API is for ZFS internal use only and is
subject to change at any time. This is true for OpenSolaris as well.
We, of course, can bump __FreeBSD_version if it helps, but one shouldn't
expect libzfs API being stable or there is any care taken to maintain
backward compatibility.
