Add ovs_flow, ovs_vport and ovs_datapath to the families supported in C. ovs-flow has some circular nesting which is fun to deal with, but the necessary support has been added already in the previous release cycle. Add a sample that proves that dealing with fixed headers does actually work correctly.
