include: Add a flow_join operation for broadcast
This adds a new flow_join operaiton for broadcast, which is a much
safer solution than overloading destination name semantics. The
internal API now also has a different IPCP_FLOW_JOIN operation. The
IRMd doesn't need to query broadcasts IPCPs for the name, it can just
check if an IPCP with the layer name exists. The broadcast IPCP
doesn't need to implement the query proxy call anymore.
