Now that the earlier DB outage is taken care of, I'm running the DB
schema changelets which have held back main code updates on the live
site since the week before Wikimania.
Updates to image, oldimage, and archive tables are being applied on the
slave servers. The new additions will:
* Speed up user renames
* Allow cleaner lookups of uploaded files by name
* Store of file content hashes for various purposes
* Store page_id of deleted pages for later use in restore or other
sorting out of fun situations
There will be intermittent slave lag while these run.
Once all the slaves are done, we'll have to swap masters and run them on
the old masters before updating code.
