Update dovecot2 to 2.2.28, and bump PORTREVISION on the plugins.

* director: "doveadm director move" to same host now refreshes user's
    timeout. This allows keeping user constantly in the same backend by
    just periodically moving the user there.
  * When new mailbox is created, use initially INBOX's
    dovecot.index.cache caching decisions.
  * Expunging mails writes GUID to dovecot.index.log now only if the
    GUID is quickly available from index/cache.
  * pop3c: Increase timeout for PASS command to 5 minutes.
  * Mail access errors are no longer ignored when searching or sorting.
    With IMAP the untagged SEARCH/SORT reply is still sent the same as
    before, but NO reply is returned instead of OK.

  + Make dovecot.list.index's filename configurable. This is needed when
    there are multiple namespaces pointing to the same mail root
    (e.g. lazy_expunge namespace for mdbox).
  + Add size.virtual to dovecot.index when folder vsizes are accessed
    (e.g. quota=count). This is mainly a workaround to avoid slow quota
    recalculation performance when message sizes get lost from
    dovecot.index.cache due to corruption or some other reason.
  + auth: Support OAUTHBEARER and XOAUTH2 mechanisms. Also support them
    in lib-dsasl for client side.
  + auth: Support filtering by SASL mechanism: passdb { mechanisms }
  + Shrink the mail processes' memory usage by not storing settings
    duplicated unnecessarily many times.
  + imap: Add imap_fetch_failure setting to control what happens when
    FETCH fails for some mails (see example-config).
  + imap: Include info about last command in disconnection log line.
  + imap: Created new SEARCH=X-MIMEPART extension. It's currently not
    advertised by default, since it's not fully implemented.
  + fts-solr: Add support for basic authentication.
  + Cassandra: Support automatically retrying failed queries if
    execution_retry_interval and execution_retry_times are set.
  + doveadm: Added "mailbox path" command.
  + mail_log plugin: If plugin { mail_log_cached_only=yes }, log the
    wanted fields only if it doesn't require opening the email.
  + mail_vsize_bg_after_count setting added (see example-config).
  + mail_sort_max_read_count setting added (see example-config).
  + pop3c: Added pop3c_features=no-pipelining setting to prevent using
    PIPELINING extension even though it's advertised.

  - Index files: day_first_uid wasn't updated correctly since v2.2.26.
    This caused dovecot.index.cache to be non-optimal.
  - imap: SEARCH/SORT may have assert-crashed in
    client_check_command_hangs
  - imap: FETCH X-MAILBOX may have assert-crashed in virtual mailboxes.
  - imap: Running time in tagged command reply was often wrongly 0.
  - search: Using NOT n:* or NOT UID n:* wasn't handled correctly
  - director: doveadm director kick was broken
  - director: Fix crash when using director_flush_socket
  - director: Fix some bugs when moving users between backends
  - imapc: Various error handling fixes and improvements
  - master: doveadm process status output had a lot of duplicates.
  - autoexpunge: If mailbox's rename timestamp is newer than mail's
    save-timestamp, use it instead. This is useful when autoexpunging
    e.g. Trash/* and an entire mailbox is deleted by renaming it under
    Trash to prevent it from being autoexpunged too early.
  - autoexpunge: Multiple processes may have been trying to expunge the
    same mails simultaneously. This was problematic especially with
    lazy_expunge plugin.
  - auth: %{passdb:*} was empty in auth-worker processes
  - auth-policy: hashed_password was always sent empty.
  - dict-sql: Merge multiple UPDATEs to a single statement if possible.
  - fts-solr: Escape {} chars when sending queries
  - fts: fts_autoindex_exclude = \Special-use caused crashes
  - doveadm-server: Fix leaks and other problems when process is reused
    for multiple requests (service_count != 1)
  - sdbox: Fix assert-crash on mailbox create race
  - lda/lmtp: deliver_log_format values weren't entirely correct if Sieve
    was used. especially %{storage_id} was broken.
  - lmtp_user_concurrency_limit didn't work if userdb changed username
