[libvirt PATCH 1/9] qemu: start the D-Bus daemon as needed

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

The daemon is started on daemon in external devices and hotplug code.
Add a mechanism to start it before qemu, if qemu itself needs it. (it is
already stopped in qemuProcessStop)
