Per documentation on IDatabase, $conds must be a string or an array.
Passing false for conds is confusing, since it's unclear whether this
should match everything or nothing.

Storing the user name or IP in every row in large tables like revision
and logging takes up space and makes operations on these tables slower.
This patch begins the process of moving those into one "actor" table
which other tables can reference with a single integer field.
A subsequent patch will remove the old columns.
