Several classes have a "selectFields()" static method to tell callers
which fields to select from the database. With the recent comment table
change and the upcoming actor table change, this pattern has become too
simplistic as a SELECT will need to join several tables to be able to
retrieve all the needed fields.
Thus, we deprecate the selectFields() methods in favor of getQueryInfo()
methods that return tables and join conditions in addition to the
fields.

To work around an optimizer bug in MySQL where the
index on (rev_page, rev_id) is picked which mysteriously
leads to very slow execution times and timeouts.
In theory, the index being forced here is (rev_id),
which is fine for this query. In WMF production,
it can also be (rev_id, rev_user) (still fine), or
(rev_page, rev_id) (the index we're trying to avoid).
Mysteriously, the optimizer bug doesn't happen if
(rev_page, rev_id) is the primary key, so this still
behaves OK.

This paramater contains a map of id => old and new visibility bits.
This allows doPostCommitUpdates to do something useful with the
differences before and after a visibility change. Specifically,
RevDelRevisionList doPostCommitUpdates passes this to the
ArticleRevisionVisibilitySet hook.
