vlan: Add GVRP support
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.
