Update dovecot2 to 2.2.31, and bump PORTREVISION on the modules.

* LMTP: Removed "(Dovecot)" from added Received headers. Some
  installations want to hide it, and there's not really any good reason
  for anyone to have it.

+ Add ssl_alt_cert and ssl_alt_key settings to add support for
  having both RSA and ECDSA certificates.
+ dsync/imapc, pop3-migration plugin: Strip trailing whitespace from
  headers when matching mails. This helps with migrations from Zimbra.
+ acl: Add acl_globals_only setting to disable looking up
  per-mailbox dovecot-acl files.
+ Parse invalid message addresses better. This mainly affects the
  generated IMAP ENVELOPE replies.
- v2.2.30 wasn't fixing corrupted dovecot.index.cache files properly.
  It could have deleted wrong mail's cache or assert-crashed.
- v2.2.30 mail-crypt-acl plugin was assert-crashing
- v2.2.30 welcome plugin wasn't working
- Various fixes to handling mailbox listing. Especially related to
  handling nonexistent autocreated/autosubscribed mailboxes and ACLs.
- Global ACL file was parsed as if it was local ACL file. This caused
  some of the ACL rule interactions to not work exactly as intended.
- auth: forward_* fields didn't work properly: Only the first forward
  field was working, and only if the first passdb lookup succeeded.
- Using mail_sort_max_read_count sometimes caused "Broken sort-*
  indexes, resetting" errors.
- Using mail_sort_max_read_count may have caused very high CPU usage.
- Message address parsing could have crashed on invalid input.
- imapc_features=fetch-headers wasn't always working correctly and
  caused the full header to be fetched.
- imapc: Various bugfixes related to connection failure handling.
- quota=imapc sent unnecessary FETCH RFC822.SIZE to server when
  expunging mails.
- quota=count: quota_warning = -storage=.. was never executed
- quota=count: Add support for "ns" parameter
- dsync: Fix incremental syncing for mails that don't have Date or
  Message-ID headers.
- imap: Fix hang when client sends pipelined SEARCH +
  EXPUNGE/CLOSE/LOGOUT.
- oauth2: Token validation didn't accept empty server responses.
- imap: NOTIFY command has been almost completely broken since the
  beginning. I guess nobody has been trying to use it.

Add an upstream patch to fix a potential crash or a scenario where
mail is mis-marked as corrupted.
