    tipc: let broadcast packet reception use new link receive function · 52666986

    The code path for receiving broadcast packets is currently distinct
    from the unicast path. This leads to unnecessary code and data
    duplication, something that can be avoided with some effort.
    
    We now introduce separate per-peer tipc_link instances for handling
    broadcast packet reception. Each receive link keeps a pointer to the
    common, single, broadcast link instance, and can hence handle release
    and retransmission of send buffers as if they belonged to the own
    instance.
    
    Furthermore, we let each unicast link instance keep a reference to both
    the pertaining broadcast receive link, and to the common send link.
    This makes it possible for the unicast links to easily access data for
    broadcast link synchronization, as well as for carrying acknowledges for
    received broadcast packets.
