Peter Krempa fe027c9b0a virCPUx86DataGetHost: Fix construction of the returned data
The function returns 'virCPUData' but doesn't do two important steps
which other code takes:

1) leaves with all-zero data is stripped from the XML output
2) the data is expected to be sorted in the array

Now the 'virHostCPUGetCPUID' helper returns both all 0 leaves and
doesn't order them as we expect.

If this is then used in conjunction with 'virCPUx86DataIsIdentical'
together with data which made a roundtrip to XML and back the result
will be always false even if the data itself is identical.

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
