    Implement poll support.  Polled files are indexed using kh in a RB
    tree rooted at fuse_conn->polled_files.
    
    Client should send FUSE_NOTIFY_POLL notification once after processing
    FUSE_POLL which has FUSE_POLL_SCHEDULE_NOTIFY set.  Sending
    notification unconditionally after the latest poll or everytime file
    content might have changed is inefficient but won't cause malfunction.
    
    fuse_file_poll() can sleep and requires patches from the following
    thread which allows f_op->poll() to sleep.
