This removes most of the pre-actor user and user_text columns, and the $wgActorTableSchemaMigrationStage setting that used to determine whether the columns were used. rev_user and rev_user_text remain in the code, as on Wikimedia wikis the revision table is too large to alter at this time. A future change will combine that with the removal of rev_comment, rev_content_model, and rev_content_format (and the addition of rev_comment_id and rev_actor). ActorMigration's constructor continues to take a $stage parameter, and continues to have the logic for handling it, for the benefit of extensions that might need their own migration process. Code using ActorMigration for accessing the core fields should be updated to use the new actor fields directly. That will be done for in a followup.
