There was a report on libvirt-users [1] about the domxml to/from
native converter in the Xen driver not handling PCI addresses
without a domain specification. This patch improves parsing of PCI
addresses in the converter and allows PCI addresses with only
bb:ss.f. xl.cfg(5) also allows either the dddd:bb:ss.f or bb:ss.f
format. A test has been added to check the conversion from xl.cfg
to domXML.
