David Woodhouse 766804b101 hw/xen: Implement core serialize/deserialize methods for xenstore_impl 
This implements the basic migration support in the back end, with unit
tests that give additional confidence in the node-counting already in
the tree.

However, the existing PV back ends like xen-disk don't support migration
yet. They will reset the ring and fail to continue where they left off.
We will fix that in future, but not in time for the 8.0 release.

Since there's also an open question of whether we want to serialize the
full XenStore or only the guest-owned nodes in /local/domain/${domid},
for now just mark the XenStore device as unmigratable.
