[libvirt] PATCH: Test the QEMU argv -> XML convertor

This patch adds a test case which validates the argv -> XML convertor for QEMU. This re-uses the existing XML data files from the XML -> argv test. This has a few complications though because we can't roundtrip all the data. So I have a couple really seriously evil regexes which splice out the XML lines we know won't match - name, uuid, memory and disk sharing modes. This isn't ideal, but I figure it is better todo this and get coverage over 90% of the code, than to have no test coverage.
