+ o Add silc_stream_get_root and add get_root stream operation. It
+ returns the root of the stream or NULL if stream doesn't have root.
+ Like SilcPacketStream might return SilcSocketStream.
+
+ o Change some stream routines (like socket stream API) to accept ANY
+ stream and use silc_stream_get_root to get the socket stream from the
+ given stream. This will make various stream APIs more easier to use
+ when user doesn't have to dig up the correct stream.
