  ui/virtio-gpu: add and use qemu_create_displaysurface_pixman

Add a the new qemu_create_displaysurface_pixman function, to create
a DisplaySurface backed by an existing pixman image.  In that case
there is no need to create a new pixman image pointing to the same
backing storage.  We can just use the existing image directly.

This does not only simplify things a bit, but most importantly it
gets the reference counting right, so the backing storage for the
pixman image wouldn't be released underneath us.

Use new function in virtio-gpu, where using it actually fixes
use-after-free crashes.

  virtio-gpu: block live migration

Feeling a bit nervous putting the full live migration support
patch (https://patchwork.ozlabs.org/patch/606902/) in that
late in the 2.6 devel cycle as it carries some non-trivial
changes.  So disable migration in case virtio-gpu is present
for now.
