If libvirt specifies LIBXL_API_VERSION then it does not need to check
any LIBXL_HAVE_*, since it will actually get an API corresponding to
the specified API_VERSION.
This cant be true, because otherwise it will be unable to use vscsi and
perhaps usb (and whatever else showed up after 4.2).
Does that also mean that for example things related to LIBXL_HAVE_VSCSI
need to be wrapped in "#if LIBXL_API_VERSION > $whatever"? Maybe I'm
just misunderstand what you are trying to say.
