    bug 1057844: improve floating-ip association checks

    allow multiple floating ips to be associated with the same internal port
    as long as they map to different external nets (not yet supported in
    Folsom) or different internal fixed IPs. With Quantum, there is no
    need to disallow either scenario.

    Also improve check for a valid external network to router to internal
    subnet path when a floating IP is bound.
