This patch set enables cpu model support for s390. The user can now set exact
cpu models, query supported models via virsh domcapabilities, and use host-model
and host-passthrough modes. The end result is that migration is safer because
Qemu will perform runnability checking on the destination host and quit with an
error if the guest's cpu model is not supported.
Note: Some test data has been separated from corresponding test case updates for
ease of review.
