Peter Krempa 02f0f1ccc7 tests: qemuxml2xml: Test status XML formatting and parsing 
Recently we've fixed a bug where the status XML could not be parsed as
the parser used absolute path XPath queries. This test enhancement tests
all XML files used in the qemu-xml-2-xml test as a part of a status XML
snippet to see whether they are parsed correctly. The status XML-2-XML is
currently tested in 223 cases with this patch.
