Having libvirt probe the -help output is out of the question.  We
already declared that for qemu 1.3 and beyond, ALL command line behavior
must ALSO be probe-able via QMP.  I think Anthony had a trick for
testing for existence of various command line options without needing to
add a new query-strict-boot command, but I don't remember what that
trick was.
