[Libvir] PATCH: Autodetect QEMU version

When I tested out the libvirt 0.2.0 in Fedora rawhide I discovered that the syntax for specifying VNC display numbers changes in QEMU 0.9.0. Previously you would use -vnc 7 Now you need to use -vnc :7 For current Fedora RPM I just hacked in a workaround to always add ':', but we need to be able to detect the version properly. So I'm attaching a patch which spawns '/usr/bin/qemu' and groks its command line help to extract the version number. It then uses appropriate VNC argument syntax based on the version. At the same time I also check for whether -no-kqemu is available so we can turn off KQEMU support if it is not available.
