Commit 1607335 from [~gemmellr] in branch 'proton/trunk'
[ https://svn.apache.org/r1607335 ]

PROTON-543: document that Transport#sasl() must be called prior to any processing if a sasl layer is desired. Throw ISE from sasl() if process() has been called before the first sasl() invocation.

> If the input stream is read and passed into the transport, before the sasl() method of TransportImpl.java is called then the _inputProcessor defaults to FrameParser instead of being wrapped by the SASL frame parser.
> This causes a Frame Parsing error as it expects '0' as per the regular header but instead finds '3' which is the correct format if the process is the SASL frame parser.
> As per the discussion on @proton we decide to throw an exception if sasl is set after the input stream has been processed.
