[libvirt] [PATCH] Add the device alias element to the domain.rng schema



Every device element that can contain an address element
can also contain an alias element, but the domain.rng didn't
reflect this. Therefore, running virt-xml-validate on the
virsh dumpxml output of an active domain failed. It doesn't
fail for inactive domains, because in that case dumpxml
doesn't include the alias elements.

Add the device alias element to the domain.rng schema and
add a new test case to cover this.

Indirectly reported by Jon Stanley.
