[libvirt PATCH v6 10/30] nodedev: add DEFINED/UNDEFINED lifecycle events

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Since a mediated device can be persistently defined by the mdevctl
backend, we need additional lifecycle events beyond CREATED/DELETED to
indicate that e.g. the device has been stopped but the device definition
still exists.
