Creates a DataInputStream and a DataOutputStream from the given raw streams and
pushes these as the current streams to use for communication for a connection.
Returns the next byte in the input stream without removing it. Returns zero if no bytes are
available. This method will wait for up to maxWaitMillis milliseconds to allow pending data to
become available in the buffer.
