[Dovecot] v1.2.9 released

http://dovecot.org/releases/1.2/dovecot-1.2.9.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.9.tar.gz.sig

Hopefully this release will be enough bug-free that I don't need to make v1.2 releases for next few months.

* maildir: When saving, filenames now always contain ,S=<size>.
  Previously this was done only when quota plugin was loaded. It's
  required for zlib plugin and may be useful for other things too.

+ lazy-expunge: Support a single-namespace configuration. If a mailbox
  is deleted, its messages are merged with its old expunged messages
  (if there were any).
+ expire: Settings now support spaces in mailbox names by using
  quoted strings.
- maildir: v1.2.7 and v1.2.8 caused assert-crashes in
  maildir_uidlist_records_drop_expunges()
- maildir_copy_preserve_filename=yes could have caused crashes.
- Maildir++ quota: % limits weren't updated when limits were read
  from maildirsize.
- virtual: v1.2.8 didn't fully fix the "lots of mailboxes" bug
- virtual: Fixed updating virtual mailbox based on flag changes.
- fts-squat: Fixed searching multi-byte characters.
