Update Information:

fixes CVE-2015-3420: SSL/TLS handshake failures leading to a crash of the login process
- dovecot updated to 2.2.16
- auth: Don't crash if master user login is attempted without
  any configured master=yes passdbs
- Parsing UTF-8 text for mails could have caused broken results
  sometimes if buffering was split in the middle of a UTF-8 character.
  This affected at least searching messages.
- String sanitization for some logged output wasn't done properly:
  UTF-8 text could have been truncated wrongly or the truncation may
  not have happened at all.
- fts-lucene: Lookups from virtual mailbox consisting of over 32
  physical mailboxes could have caused crashes.
