I noticed this with the recent iothread pinning code, but the
problem existed longer than that. The XML validation required
users to supply <cputune> children in a strict order, even though
there was no conceptual reason why they can't occur in any order.

Add an option 'iothreadpin' to the <cpuset> to allow for setting the
CPU affinity for each IOThread.
The iothreadspin will mimic the vcpupin with respect to being able to
assign each iothread to a specific CPU, although iothreads ids start
at 1 while vcpu ids start at 0. This matches the iothread naming scheme.
