    iface: merge BSD/Linux interface add/keep code
    
    It now works as as follows:
    - mark all iface_dev entries as delete
    - create list of raw interfaces
    - merge raw iface and iface_dev lists, either adding or keeping
    - for added iface_dev entries create iface_port / listener
    - for still deleted entries, delete (optional)
