Awesome that we've enhanced the testsuite to check RNG parser rejection
of invalid xml!

Should we be tweaking things for the other xml files (renaming files
and/or tightening RNG) so that other uses of DO_TEST_PARSE_ERROR can
also stress RNG validation?

tests/qemuxml2argvtest.c:    DO_TEST_PARSE_ERROR("boot-dev+order",
tests/qemuxml2argvtest.c:    DO_TEST_PARSE_ERROR("usb-ich9-no-companion",
tests/qemuxml2argvtest.c:    DO_TEST_PARSE_ERROR("usb-none-other",
tests/qemuxml2argvtest.c:    DO_TEST_PARSE_ERROR("usb-none-hub",
tests/qemuxml2argvtest.c:    DO_TEST_PARSE_ERROR("usb-none-usbtablet",
