[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. Thanks to Cole for this testsuite
suggestion
