    vhost: manage FD with epoll

    Switch to epoll so that the concern over the poll() fd array
    is removed.
    Add a simple list of used entries and track the next free entry.

    epoll() is thread safe, we no more need a synchronization
    mechanism and so can remove the notification pipe.
