mod_pubsub_feeds: Track latest timestamp seen in feeds instead of last poll
This should ensure that an entry that has a publish timestmap after the
previously oldest post, but before the time of the last poll check, is
published to the node.
Previously if an entry would be skipped if it was published at 13:00
with a timestamp of 12:30, where the last poll was at 12:45.
For feeds that lack a timestamp, it now looks for the first post that is
not published, assuming that the feed is in reverse chronological order,
then iterates back up from there.

--- labels: - 'Stage-Alpha' - 'Type-Storage' summary: Experimental map store optimized for small incremental changes ... This is an experimental storage driver where changed data is appended. Data is simply written as `key = value` pairs to the end of the file. This allows changes to individual keys to be written without needing to write out the entire object again, but reads would grow gradually larger as it still needs to read old overwritten keys. This may be suitable for e.g. rosters where individual contacts are changed at a time. In theory, this could also allow rolling back changes. Requires 0.10
