Add GVRP support for dynamically registering VLANs with switches. By default GVRP is disabled because we only support the applicant-only participant model, which means it should not be enabled on vlans that are members of a bridge. Since there is currently no way to cleanly determine that, the user is responsible for enabling it. The code is pretty small and low impact, its wrapped in a config option though because it depends on the GARP implementation and the STP core.
