multi-dbox users: Be careful about the INDEX change.

Maildir users: I hope v2.0 is now finally stable.

	* multi-dbox: If :INDEX=path is specified, keep
	  storage/dovecot.map.index* files also in the index path rather than
	  in the main storage directory.

	  WARNING: if you specified :INDEX= with earlier mdbox installation,
	  you must now manually move the storage indexes to the expected
	  directory! Otherwise Dovecot won't see them and will rebuild the
	  indexes, possibly unexpunging some mails.

	- Maildir: Copying messages with hard links sometimes caused the
	  source maildir's entire tmp/ directory to be renamed to destination
	  maildir as if it were a message.
	- Maildir: v2.0.3 broke expunging copied messages sometimes
	- Maildir: INBOX whose tmp/ directory was lost couldn't be opened
	- single-dbox: Messages weren't copied with hard links
	- vpopmail support is hopefully working again.
	- dsync: POP3 UIDLs weren't copied with Maildir
	- dict file: Fixed fd leak (showed up easily with LMTP + quota)
