While we're at it, let's clean up the xm commands too. I tihnk its
pointless letting the user specify the vcpu they want to enable/disable.
Let's change the command names to vcpu-add / vcpu-remove and have them
work on the lowest numbered free vcpu in the case of vcpu-add and the
highest currently active in the case of vcpu-remove.
