This adds vhost net support in qemu. Will be tied to tap device and
virtio later. Raw backend is currently missing, will be worked
on/submitted separately.

Don't know how to make queuefd work: probably need support for binding
hypercalls to eventfd in kvm? Again, just a demonstration, probably not
for commit, because s390 does not have vector support.

No idea if it's right .. and syborg does not support vectors so we won't
get performance gains out of it either - so quite likely it's best to
just keep this patch out of qemu. But just to show what's possible.

Support irqfd/queuefd. The last one only with kvm, that's
okay because vhost relies on kvm anyway.

Here's an untested patchset with vhost support for upstream qemu. Note
that you should not expect performance gains from vhost unless in-kernel
irqchip is enabled (which is not in upstream qemu now). Since adding
vhost involves quite a bit of infrastructure, I thought it makes sense
to send an RF

Since patch ed757e140c0ada220f213036e4497315d24ca8bct, virtio will
sometimes clear all status registers on bus master disable, which loses
information such as VIRTIO_CONFIG_S_FAILED bit. This is a result of
