See the "ACL handling bugs" message for more details about the ACL
merging bug.

	* acl: Fixed the logic of merging multiple ACL entries. Now it works as
	  documented, while previously it could have done slightly different
	  things depending on the order of the entries.

	* acl: Don't give admin rights to all owner mailboxes. This was
	  originally done to make sure that mailbox owner couldn't accidentally
	  remove their own admin rights. But this is already prevented by
	  SETACL command, so it's not necessary. Also sysadmin may have
	  intentionally removed some admin rights from some mailboxes
	  (especially when using symlinked shared mailboxes).

	- Maildir: Fixed potential "Duplicate file entry" in dovecot-uidlist
	  file errors.
	- Maildir: Avoid unnecessary uidlist recreation during mail delivery.
	- imap: When SELECT fails, it didn't close the previous mailbox.
	- Dovecot master process could have died if it got SIGCHLD signals
	  very rapidly while it was trying to log. This could have happened
	  for example if a lot of imap/pop3 sessions disconnected at the exact
	  same time.
