  -----------
  auth: client protocol: Recognize empty initial response field as an absent initial response for older clients.

Particularly, Exim sends an empty initial response field in the AUTH request for
an authentication command that has no initial response. Originally, Dovecot
allowed this, but this was recently changed so that the EXTERNAL SASL mechanism
works properly from ManageSieve. This commit makes it allowed again for older
authentication clients to send an empty initial response field for an
authentication command that has no initial response part. Sending '=' for an
empty initial response is still allowed in general.
