Log Message:
Update to Dovecot 1.1.1.  Beta's and RC's have been tracked in pkgsrc-wip,
copy from there.

Update the Sieve plugin accordingly to 1.1.5.

Major changes since 1.0:

	* After Dovecot v1.1 has modified index or dovecot-uidlist files,
	  they can't be opened anymore with Dovecot versions earlier than
	  v1.0.2.
	* See doc/wiki/Upgrading.1.1.txt (or for latest changes,
	  http://wiki.dovecot.org/Upgrading/1.1) for list of changes since
	  v1.0 that you should be aware of when upgrading.

	+ IMAP: Added support for UIDPLUS and LIST-EXTENDED extensions.
	+ IMAP SORT: Sort keys are indexed, which makes SORT commands faster.
	+ When saving messages, update cache file immediately with the data
	  that we expect client to fetch later.
	+ NFS caches are are flushed whenever needed. See mail_nfs_storage and
	  mail_nfs_index settings.
	+ Out of order command execution (SEARCH, FETCH, LIST), nonstandard
	  command cancellation (X-CANCEL <tag>)
	+ IMAP: STATUS-IN-LIST draft implementation
	+ Expire plugin can be used to keep track of oldest messages in
	  specific mailboxes. A nightly run can then quickly expunge old
	  messages from the mailboxes that have them. The tracking is done
	  using lib-dict, so you can use either Berkeley DB or SQL database.
	+ Namespaces are supported everywhere now.
	+ Namespaces have new list and subscriptions settings.
	+ Full text search indexing support with Lucene and Squat backends.
	+ OTP and S/KEY authentication mechanisms (by Andrey Panin).
	+ mbox and Maildir works with both Maildir++ and FS layouts. You can
	  change these by appending :LAYOUT=3Dmaildir++ or :LAYOUT=3Dfs to
	  mail_location.
	+ LDAP: Support templates in pass_attrs and user_attrs
	+ Support for listening in multiple IPs/ports.
	+ Quota plugin rewrite: Support for multiple quota roots, warnings,
	  allow giving storage size in bytes or kilo/mega/giga/terabytes,
	  per-mailbox quota rules.
	+ Filesystem quota backend supports inode limits, group quota and
	  RPC quota for NFS.
	+ SEARCH and SORT finally compare non-ASCII characters
	  case-insensitively. We use i;unicode-casemap algorithm.
	+ Config files support splitting values to multiple lines with \
