[libvirt] [PATCH 05/16] network: Move macmap mgmt from bridge_driver to virnetworkobj



In preparation for having a private virNetworkObj - let's create/move some
API's that handle the obj->macmap. The API's will be renamed to have a
virNetworkObj prefix to follow conventions and the arguments slightly
modified to accept what's necessary to complete their task.
