[meta-virtualization] [RFC] Separate Xen toolstack from hypervisor

[M. Gregory]

Xen supports a variety of toolstacks, xl, libvirt, and xapi. Would it be
acceptable to the meta-virtualization community to divide the Xen recipe
into two separate recipes, one for the hypervisor and one for currently
supported xl toolstack? With the possibility of including a xapi recipe
in the future?
