From: Marc-André Lureau <marcandre.lureau(a)redhat.com>
This code was based on a per-helper instance and peer-to-peer
connections. The code that landed in qemu master for v5.0 is relying
on a single instance and DBus bus.
Instead of trying to adapt the existing dbus-vmstate code, let's
remove it and resubmit. That should make reviewing easier.
