mod_blocklist: Add option 'migrate_legacy_blocking' to disable migration from mod_privacy Tiny performance improvement for new users by skipping this check. Most servers should have gone trough the migration for all active users long ago. As a suitable first step of phasing out this code, we make it possible to disable it first. Later it can be disabled by default, before finally the code is deleted.
