    kevent: Restore old EV_EOF semantics
    
    - EV_EOF should be set when the other side closed the connection, even
      if there are data pending in the read buffer (the old semantics).
    - EV_NODATA is added to indicate there are no more data pending in the
      buffer and EOF is detected (EV_EOF is also set in this situation).
    
    Kernel code now tests EV_NODATA instead of EV_EOF, since EV_NODATA
    delivers the information which was delivered by the EV_EOF before
    this commit.
