This will allow SVQ to add context to the different queue elements.
This patch only store the actual element, no functional change intended.

VirtQueueElement comes from the guest, but we're heading SVQ to be able
to modify the element presented to the device without the guest's
knowledge.
To do so, make SVQ accept sg buffers directly, instead of using
VirtQueueElement.
Add vhost_svq_add_element to maintain element convenience.

A guest's buffer continuos on GPA may need multiple descriptors on
qemu's VA, so SVQ should track its length sepparatedly.

This allows external handlers to be aware of new buffers that the guest
places in the virtqueue.
When this callback is defined the ownership of the guest's virtqueue
element is transferred to the callback. This means that if the user
wants to forward the descriptor it needs to manually inject it.

Do a simple forwarding of CVQ buffers, the same work SVQ could do but
through callbacks. No functional change intended.

Since the vhost-vdpa device is exposing _F_LOG, adding a migration blocker if
it uses CVQ.
However, qemu is able to migrate simple devices with no CVQ as long as
they use SVQ. To allow it, add a placeholder error to vhost_vdpa, and
only add to vhost_dev when used. vhost_dev machinery place the mig

Hi David,
Thanks for your feedback. I'll CC you on v+1. Note that I don't know
very much about s390x, so I may require some slight hand holding, but
let's see how far I can get...
