/**
* 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,...)
