Update dovecot to 2.2.30, and bump PORTREVISION in consumers.

* auth: Use timing safe comparisons for everything related to
  passwords. It's unlikely that these could have been used for
  practical attacks, especially because Dovecot delays and flushes all
  failed authentications in 2 second intervals. Also it could have
  worked only when passwords were stored in plaintext in the passdb.
* master process sends SIGQUIT to all running children at shutdown,
  which instructs them to close all the socket listeners immediately.
  This way restarting Dovecot should no longer fail due to some
  processes keeping the listeners open for a long time.

+ auth: Add passdb { mechanisms=none } to match separate passdb lookup
+ auth: Add passdb { username_filter } to use passdb only if user
  matches the filter. See https://wiki2.dovecot.org/PasswordDatabase
+ dsync: Add dsync_commit_msgs_interval setting. It attempts to commit
  the transaction after saving this many new messages. Because of the
  way dsync works, it may not always be possible if mails are copied
  or UIDs need to change.
+ imapc: Support imapc_features=search without ESEARCH extension.
+ imapc: Add imapc_features=fetch-bodystructure to pass through remote
  server's FETCH BODY and BODYSTRUCTURE.
+ imapc: Add quota=imapc backend to use GETQUOTA/GETQUOTAROOT on the
  remote server.
+ passdb imap: Add allow_invalid_cert and ssl_ca_file parameters.
+ If dovecot.index.cache corruption is detected, reset only the one
  corrupted mail instead of the whole file.
+ doveadm mailbox status: Add "firstsaved" field.
+ director_flush_socket: Add old host's up/down and vhost count as parameters
- More fixes to automatically fix corruption in dovecot.list.index
- dsync-server: Fix support for dsync_features=empty-header-workaround
- imapc: Various bugfixes, including infinite loops on some errors
- IMAP NOTIFY wasn't working for non-INBOX if IMAP client hadn't
  enabled modseq tracking via CONDSTORE/QRESYNC.
- fts-lucene: Fix it to work again with mbox format
- Some internal error messages may have contained garbage in v2.2.29
- mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys
  are used. Otherwise the copied mails can't be opened.
- vpopmail: Fix compiling
