  Log Message:
  -----------
  dsync: Add per-mailbox sync lock that is always used.

Both importing and exporting gets the lock before they even sync the
mailbox. The lock is kept until the import/export finishes. This guarantees
that no matter how dsync is run, two dsyncs can't be working on the same
mailbox at the same time.

This lock is in addition to the optional per-user lock enabled by the -l
parameter. If the -l parameter is used, the same lock timeout is used for
the per-mailbox lock. Otherwise 30s timeout is used.

This should help to avoid email duplication when replication is enabled for
public namespaces, and maybe in some other rare situations as well.

  Log Message:
  -----------
  dsync: Add missing transaction flags when performing UID renumbering

The transaction didn't have MAILBOX_TRANSACTION_FLAG_SYNC or
MAILBOX_TRANSACTION_FLAG_NO_NOTIFY (with DSYNC_BRAIN_FLAG_NO_NOTIFY).

This caused replication-dsync to unnecessarily trigger another dsync
replication notification.
