Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Add comment about include guard.

Log message:
Update to Dovecot 1.1.13, there were two regressions in 1.1.12:

- v1.1.12's MAILBOXDIR changes broke accessing mails in some setups
- v1.1.12's login_executable -D checking changes caused dovecot to
  crash at startup if protocols setting contained only pop3.
- mbox: pop3_lock_session=3Dyes was broken with mail_privileged_group.

Log message:
Update to Dovecot 1.1.12.  Changes since 1.1.11:

* Added :MAILBOXDIR= to mail_location to specify the root dir for
  mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes",
  because that's going to be the default in v1.2+.

+ Linux: Adding -D parameter to login_executable makes login processes
  dump core to login_dir if they crash.
- IMAP: SELECT didn't always return first unseen message in reply
- POP3: pop3_lock_session=yes didn't use mail_privileged_group while
  dotlocking.
- mbox: Don't crash if >=8192 bytes long line begins with "From ".
- Maildir: More fixes to handling over 26 keywords.
- Several logging fixes and improvements
- Fixed authentication caching with non-plaintext mechanisms when using
  a blocking passdb (e.g. MySQL)
- Fixed DIGEST-MD5 authentication with user@domain style usernames.

Log message:
Update to Dovecot 1.1.11.

- IMAP: PERMANENTFLAGS list didn't contain \*, causing some clients
  not to save keywords.
- dbox: INTERNALDATE and save date was returned wrong for converted
  maildir files.
- auth: Using "username" or "domain" passdb fields caused \ 
problems
  with cache and blocking passdbs in v1.1.8 .. v1.1.10.
- userdb prefetch + blocking passdbs was broken with non-plaintext
  auth in v1.1.8 .. v1.1.10.
- If mail_chroot is set, don't fail at startup in dump-capability.

Log message:
Update to Dovecot 1.1.10.

- Maildir: Keyword handling was somewhat broken in v1.1.9
- userdb prefetch was broken with blocking passdbs in v1.1.9
- dict process didn't always die with the rest of Dovecot
- dict quota was somewhat broken with pgsql

Log message:
Update to Dovecot 1.1.9.  From the release announcement mail:

Lots of small dbox fixes, hopefully migrations from Maildir are now working
correctly.

+ Sending SIGUSR2 to dovecot-auth now also logs statistics about cache inserts.
  This could help figuring out auth cache size.
+ deliver: Added rejection_subject setting, which is used for rejected mails.
+ pop3: Prevent clients from looping forever trying to fetch an expunged
  message.
+ If login process crashes, log the IP address that (maybe) caused it.
+ If core dump limit is 0, add "core dumps disabled" to startup log line.
+ Log better messages for "Permission denied" errors
- mbox: Fixed assert-crash with pop3_lock_session=yes
- dbox: Fixes to handling maildir-converted files.
- Auth cache wasn't working correctly for all fields (e.g. allow_nets) with
  blocking passdbs (e.g. mysql).
- pgsql: Handle reconnecting to server without failing auth lookups.
- Berkeley DB memory/resource leak fixes.
- maildir: Fixes to handling over 26 keywords.

Log message:
Updated mail/dovecot to 1.1.8

Most importantly mbox bugfixes. v1.1 should finally be as stable with
mboxes as it was with v1.0. Hopefully we'll also soon have the first
v1.2 beta release and the final v1.2.0 somewhat soon after that.

	- mbox: Several bugfixes. Fixes "next message unexpectedly lost"
          errors and perhaps some other problems as well.
	- deliver: It wasn't possible to override boolean settings in
	  lda section by setting them to "no".
	- Maildir++ quota didn't correctly check if maildirs had changed
	  during recalculation.
	- kqueue notify: Fixed assert-crash in some situations
	- dbox: Several fixes to handling Maildir migrations
	- Logging/error message improvements

Log message:
Update to Dovecot 1.1.7.  Changes since 1.1.6:

* IMAP QUOTA extension now returns "MESSAGE" quota, not \ 
"MESSAGES".
  This makes Dovecot now RFC 2087 compliant. Hopefully this change
  doesn't break anyone's Dovecot-specific quota checking code..

+ Added !include and !include_try directives to config file reader.
  Note that !include doesn't currently work with deliver. The main
  point here is that ssl_key_password can be placed to a different
  file with !include_try that deliver can just ignore.
+ More error/debug message logging improvements.
- v1.1.6 gave "userdb didn't return a home directory" error at startup
- Some config file parsers (deliver, passwd-file, acl, trash) ignored
  the file's last line if it didn't end with LF.
- fts: SEARCH SUBJECT didn't search messages that weren't already
  in fts index.
- fts-solr: Don't assert-crash if we couldn't connect to Solr.
- IMAP: Mailbox deletion gave an error, but still worked, if mails'
  control directory wasn't the same as index directory.
- Several fixes to rarely used mailbox list layout configurations.

Update to 1.1.6
Ok'ed geert@
The invalid message address parsing bug is pretty important since it
allows a remote user to send broken mail headers and prevent the
recipient from accessing the mailbox afterwards, because the process
will always just crash trying to parse the header. This is assuming that
the IMAP client uses FETCH ENVELOPE command, not all do. Note that it
doesn't affect versions older than v1.1.4.

	+ dovecot -n and -a now prints some system information at the top.
	+ More error/debug message logging improvements.
	- pop3-login: Fixed assert-crash if a client sent USER+PASS+USER+PASS
	  commands in the same IP packet.
	- Parsing an invalid message address like "From: (" caused an
	  assert-crash in v1.1.4 and v1.1.5.
	- Folding whitespace wasn't handled correctly inside quoted-strings,
	  causing some messages to be parsed incorrectly.
	- mbox: Fixed saving messages that begin with a valid From_-line.
