We used to send data like { title: { missing: true|false } }
With this change, we send data like { missing: [titles], existing: true|[titles] }
where 'existing' is set to true (assume all non-missing titles exist)
for current revisions and to an array of existing titles for
old revisions.
This is because we always output this data for links in the current
revision, even when loading an old revision: in that case we rely
on the client to request the omitted information, so there we can't
assume that all pages we don't have information about exist.
