Cyrus 2.3.12 RC1

[Ken Murchison]

I just put together a release candidate for Cyrus 2.3.12.  I'd
appreciate any independent testing before I release this to the masses.

Noteworthy changes:

* Added statuscache.db to cache IMAP STATUS data which
significantly reduces the amount of I/O necessary when neither the
mailbox nor \Seen state has changed -- courtesy of Fastmail.fm
* Added option to unexpunge to restore messages by time interval -- 
courtesy of David Carter
* Implemented undocumented IMAP SCAN extension, which allows
Pine/Alpine to do cross-mailbox searches -- based on work of David Carter
* Implemented incremental squat updates (see squatter.8) -- courtesy of 
David Carter
* Fixed major bugs in reconstruct -k implementation -- courtesy of David 
Carter

Check doc/changes.html for a complete list of changes.

If there are any outstanding issues that you believe still need to be
addressed in 2.3.12, please let me know.
