lib-master: master-auth - Add support for MAIL_AUTH_REQUEST_FLAG_IMPLICIT flag.

It signals that this login is implicit; no command reply is expected. This is
going to be used by the Submission service to implicitly login a user using the
EXTERNAL SASL mechanism when the first MAIL command is issued. In that case
sending a reply for the implicit AUTH command would break the protocol and this
new flag is used to signal the post-login submission service to not send an
initial reply.
