Marc-André Lureau 6077ae7b40 qemu: add dbus-vmstate helper migration support
Helper processes may have their state migrated with QEMU data stream
thanks to the QEMU "dbus-vmstate".

libvirt maintains the list of helpers to be migrated. The
"dbus-vmstate" is added when required, and given the list of helper
Ids that must be migrated, on save & load sides.
