    messaging: Deliver messages only once
    
    This survived an autobuild, so no subsystem strictly needs this anymore. In
    particular the notify subsystem has been rewritten.
    
    Why this patch? It removes some complexity from core code, and it reduces the
    potential memory overconsumption: Right now I'm working on a g_lock_ping_pong
    test. This test does a lot of messaging_filtered_read_send calls in a tight
    loop on a nested event context. With the current code we let the
    messaging_filtered_read code consume the message that arrives, but it also
    posts it for consumption by the main event context attached to the messaging
    context with its "classic" callback. This test never comes back to the main
    event context, so it accumulates more and more self-posted messages. That's
    just unnecessary, given that due to the successful autobuild nothing but the
    read1 test makes use of the "multicasting" of messages.
