Method unwrap

src/SecureRpcHelper.java:200–217

When QOP of auth-int or auth-conf is selected This is used to unwrap the contents from the passed buffer payload. It should be called as soon as it comes off the Netty channel. Note that the ReplayingBufferDecoder may throw an error if we are unable to read the full buffer and replay the data. @para
