Add support for API client to receive L2 MAC events
Added APIs want_l2_macs_events and l2_macs_event to allow an API client to receive notification events from VPP for MAC learned or aged in L2FIB. Only one API client is allowed for L2 MAC events. The want_l2_macs_events API allow caller to specify MAC learn limit, event scan delay and max number of MACs that can be included in a event message. These parameters should be choosen properly as to not have too many MAC events sent by VPP and overwhelm the API share memory. They can all be left as 0's so VPP will setup reasonable defaults which are: 1000 learn limit, 100 msec scan delay and 100 MACs per event message. If want_l2_macs_events is never called, VPP learning and aging should behave as before except that MAC entries provisioned by API or CLI will not be aged, even if it is not set as static_mac. These non static MACs, however, can be overwritten by MAC learning on a MAC move as a leared MAC. Only learned MACs are subject to aging.
