[libvirt] [PATCH v2 01/24] network_conf: Introduce virNetworkObjListForEach
This API will be used in the future to call passed callback over
each network object in the list. It's slightly different to its
virDomainObjListForEach counterpart, because virDomainObjList
uses a hash table to store domain object, while virNetworkObjList
uses an array.
