mod_mam: Perform message expiry based on building an index by date (backport of 39ee70fbb009 from trunk) For each day, store a set of users that have new messages. To expire messages, we collect the union of sets of users from dates that fall outside the cleanup range. The previous algoritm did not work well with many users, especially with the default settings.
