[libvirt PATCH v6 03/30] nodedev: introduce concept of 'active' node devices

[Jonathon Jongsma]

we will be able to define mediated devices that can be started or
stopped, so we need to be able to indicate whether the device is active
or not, similar to other resources (storage pools, domains, etc.)
