Changes 2.0.14:
* doveadm: Added support for running mail commands by proxying to
  another doveadm server.
* Added "doveadm proxy list" and "doveadm proxy kick" commands to
  list/kick proxy connections (via a new "ipc" service).
* Added "doveadm director move" to assign user from one server to
  another, killing any existing connections.
* Added "doveadm director ring status" command.
* userdb extra fields can now return name+=value to append to an
  existing name, e.g. "mail_plugins+= quota".
* script-login attempted an unnecessary config lookup, which usually
  failed with "Permission denied".
* lmtp: Fixed parsing quoted strings with spaces as local-part for
  MAIL FROM and RCPT TO.
* imap: FETCH BODY[HEADER.FIELDS (..)] may have crashed or not
  returned all data sometimes.
* ldap: Fixed random assert-crashing with with sasl_bind=yes.
* Fixes to handling mail chroots
* Fixed renaming mailboxes under different parent with FS layout when
  using separate ALT, INDEX or CONTROL paths.
* zlib: Fixed reading concatenated .gz files.
