Preparations to actually remove/replace `BaseDendrite`. Quite a few changes: - SyncAPI accepts an `fulltext.Indexer` interface (fulltext is removed from `BaseDendrite`) - Caches are removed from `BaseDendrite` - Introduces a `Router` struct (likely to change) - also fixes #2903 - Introduces a `sqlutil.ConnectionManager`, which should remove `base.DatabaseConnection` later on - probably more
