In a VLAN filtering bridge setup we want to be able to support an external IGMP/MLD querier running from userspace, because the bridge multicast code can only generate proxy/NULL querys per VLAN. This patch is a refactor to allow just that. If a VLAN on the bridge has an upper interface, matching the bridge name and VID, we generate a profile for querierd and enable the service. For all other cases we try to disable any running querierd. It is up to the daemon to figure out if it has a usable IP address to use as the query source IP or use 0.0.0.0. Since the logic for selecting a proper IP address must be handled by the daemon in the per-VLAN setup, we revert back to also use it for the stand-alone unfiltered bridge case as well.
