Added print_timestamp() compatibility function, this will be needed
long term but it's a simply enough addition.
Added Solaris style label functions. This was done simply to aid in
the initial update to onnv_141. I'm hopeful that after more careful
inspection all of this can be removed and we can integrate with a
more Linux friendly Solution without breaking any compatibility.
Added several missing headers which are required by the updated
version of ZFS. As usual I just add empty headers if needed because
it's easier than tracking the change against the core ZFS code.
Added SEC, MILLISEC, MICROSEC defines if unavailable.
Added missing xuio structure and typedefs. I'm hopeful these can
be removed as well once we crack the zero-copy nut under Linux.
