3351) - reported by Giles Malet

Carter for finding it and a first pass at a fix

Bron Gondwana hammering a testbed with Dovecot's imaptest tool
* Fixed compile with old PCRE (Bug #3358) - found and fixed by Simon Matter
* Fixed missing quota usage after XFER (Buf #3349) - found by Dave McMurtrie

cache errors occured.
* Fixed sync_reset handling of user deletions
* Fixed proc file handling of LOGIN and folder unselect
* use cyrus.expunge file (if still present) to delete bogus records
from a failed index upgrade (cause by bugs in earlier version)

* handle missing seen file in XFER
Changes to the Cyrus IMAP Server since 2.4.2
* Many fixes to replication edge case handling
* Added missing flags to reconstruct
* Replicate DELETED.user folders in sync_client -u (matches XFER
behaviour now)
* Make sync_client only connect after forking in rolling mode. Fixes
two things - ssl crashes due to shared resource conflicts, and also
means master will start up even if the replica is not contactable
* Fixed crash on cyr_expire and ipurge annotation based expiry
* Many XFER fixes for compatibility across versions:
* allowing XFER in from delayed_expunge mailboxes
* allowing XFER back all the way to Cyrus 2.2.12. This was
accomplished by adding logic that can generate
backwards-compatible older version indexes, and version
detection from the imapd banner.
* correctly fixing seen information for sub-mailboxes on XFER in
* Multi-target replication. Strictly this is a new feature - there
was a broken implementation in 2.4.0, which is how this snuck in to
the bugfix release. It's not super-well documented yet, but it
works by creating a separate log file for each destination
"channel", and then running one sync_client process per channel, so
replication can fall behind on one without affecting replication to
the other.
* Fixed some crashes and errors which occured when upgrading and
opening corrupted mailboxes
* Modified AFS ptloader configure options to allow building on more
modern systems
IMAP (Internet Message Access Protocol) is an Internet standards-track
protocol for accessing messages (mail, bboards, news, etc). The Cyrus
IMAP server differs from other IMAP server implementations in that it
is generally intended to be run on "sealed" servers, where normal users
are not permitted to log in. The mailbox database is stored in parts of
the filesystem that are private to the Cyrus IMAP system. All user
access to mail is through the IMAP, POP3, or KPOP protocols.
