[Dovecot] v1.1.2 release candidate

I've finally read and answered most of the mails on this list. If you haven't received an answer to your question, resend it. There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems.

There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two.

So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz

Largest changes since v1.1.1 are:

+ Added full text search indexing support for Apache Lucene Solr
  server: http://wiki.dovecot.org/Plugins/FTS/Solr
+ IMAP SORT: Added X-SCORE sort key for use with Solr searches.
+ zlib plugin supports now bzip2 also.
+ quota: All backends now take noenforcing parameter.
+ Maildir: Add ,S=<size> to maildir filename whenever quota plugin
  is loaded, even when not using Maildir++ quota.
+ deliver: Allow lda section to override plugin settings.
+ deliver: Giving a -m <namespace prefix> parameter now silently saves
  the mail to INBOX. This is useful for e.g. -m INBOX/${extension}
+ Added a new maildirlock utility for write-locking Dovecot Maildir.
+ dict-sql: Support non-MySQL databases by assuming they implement the
  "INSERT .. ON DUPLICATE KEY" using an INSERT trigger.
- SORT: Fixed several crashes/errors with sort indexing.
- IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions
  didn't include Content-Location support.
- IMAP: Fixed bugs with listing INBOX.
- Maildir: maildirfolder file wasn't created when dovecot-shared
  file existed on the root directory
- deliver didn't expand %variables in namespace location settings.
- zlib: Copying non-compressed messages resulted in empty mails
  (except when hardlink-copying between maildirs).
- mbox-snarf plugin was somewhat broken
- deliver + Maildir: If uidlist couldn't be locked while saving,
  we might have assert-crashed
