[libvirt] [PATCH 05/11] Introduce a 'stop' method to virDriverState
From: "Daniel P. Berrange" <berrange(a)redhat.com>
To allow actions to be performed in libvirtd when the host
shuts down, or user session exits, introduce a 'stop'
method to virDriverState. This will do things like saving
the VM state to a file.
