PROTON-2443: Workaround bug in cyrus sasl EXTERNAL mechanism
The mechanism plugin assumes that the initial iresponse data is zero
terminated. But this is not required by the protocol or by the API used
by cyrus sasl.

> Priority: Major

> AMQP SASL init frame contains client response data that is the requested user
> and is passed to cyrus sasl with the {{sasl_server_start()}} call. There
> should be no need for zero termination of this string as the length is passed
> in to the API.
