[Dovecot] v1.0.9 released

http://dovecot.org/releases/1.0/dovecot-1.0.9.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.9.tar.gz.sig

+ Maildir: Don't wait on dovecot-uidlist.lock when we just want to
  find out a new filename for the message.
- mbox: v1.0.8 changes sometimes caused FETCH to fail with
  "got too little data", disconnecting the client.
- Fixed a memory leak when FETCHing message header/body multiple
  times within a command (e.g. BODY[1] BODY[2])
- IMAP: Partial body fetching was still slow with mboxes
