When (un)plugging an interface into a network, the 'plugged' and 'unplugged' operations are invoked in the hook script. The data provided to the script contains the network XML, the domain XML and the domain interface XML. When we strictly split the drivers up this will no longer be possible and thus breakage is unavoidable. The hook scripts are not considered to be covered by the API guarantee so this is OK. To avoid existing scripts taking the wrong action, the existing operations are changed to 'port-created' and 'port-deleted' instead. These will receive the network XML and the network port XML.
