[Dovecot] v1.0.2 release candidate

http://dovecot.org/tmp/dovecot-1.0.2-rc.tar.gz

Unless someone finds something broken, I'll release v1.0.2 in a few days. The most important changes since v1.0.1:

* dbox isn't built anymore by default. It will be redesigned so it
  shouldn't be used.

+ Maildir: Support reading dovecot-uidlist (v3) files created by
  Dovecot v1.1.
- Maildir: "UIDVALIDITY changed" errors could happen with newly
  created mailboxes
- If "INBOX." namespace was used, LIST returned it with \HasNoChildren
  which caused some clients not to show any other mailboxes.
- Maildir++ quota: If multiple processes were updating maildirsize
  at the same time, we failed with "Unknown error".
- IMAP: IDLE didn't actually disconnect client after 30 minutes of
  inactivity.
- LDAP passdb/userdb was leaking memory
- deliver: %variables in plugin {} weren't expanded
