tools: Add nestedhvm guest config option

I don't have an objection to this.  The tools parts seem largely sane.
However, I have two queries.

Firstly, one for Christoph: is this patch safe to apply before the
relevant hypervisor features, or will it break ?  If it will break
then it should be applied later.

It is safe. nested virtualization is disabled by default. You have to add "nestedhvm=1" to your guest config file to make the guest see
hw virtualization available.

Secondly, one for the Xen.org team in general: are we accepting new
features in Xend ?  If not then I should drop the changes to xend from
this patch.
