/**
  * Close stream. This method can close both IClientBroadcastStream (coming from Flash Player to
  * Red5) and ISubscriberStream (from Red5 to Flash Player). Corresponding application handlers
  * (streamSubscriberClose, etc.) are called as if close was initiated by Flash Player.
  *
  * <p>It is recommended to remember stream id in application handlers, ex.:
  *
  * <pre>
  * public void streamBroadcastStart(IBroadcastStream stream) {
  * 	super.streamBroadcastStart(stream);
  * 	if (stream instanceof IClientBroadcastStream) {
  * 		int publishedStreamId = ((ClientBroadcastStream)stream).getStreamId();
  * 		Red5.getConnectionLocal().setAttribute(PUBLISHED_STREAM_ID_ATTRIBUTE, publishedStreamId);
  * 	}
  * }
  * </pre>
  *
  * <pre>
  * public void streamPlaylistItemPlay(IPlaylistSubscriberStream stream, IPlayItem item, boolean isLive) {
  * 	super.streamPlaylistItemPlay(stream, item, isLive);
  * 	Red5.getConnectionLocal().setAttribute(WATCHED_STREAM_ID_ATTRIBUTE, stream.getStreamId());
  * }
  * </pre>
  *
  * When stream is closed, corresponding NetStream status will be sent to stream provider /
  * consumers. Implementation is based on Red5's StreamService.close()
  *
  * @param conn client connection
  * @param streamId stream ID (number: 1,2,...)
