public class SaslInitiationHandler extends io.netty.channel.ChannelInboundHandlerAdapter
A Netty channel handler that initiates the DBus SASL authentication process by sending a NUL byte when the channel becomes active.

After successfully sending the NUL byte, this handler fires a DBusChannelEvent.SASL_NUL_BYTE_SENT user event and then removes itself from the pipeline.
