Change subject: (02/05) delta_store: convert DeltaIterator::PrepareBatch flags into bitfield ...................................................................... (02/05) delta_store: convert DeltaIterator::PrepareBatch flags into bitfield A follow-on patch will introduce DeltaIterator::SelectUpdates(), a new method for extracting delta information from a DeltaIterator. As it is only to be used by diff scans and will require dedicated in-memory state, it'll also come with a new DeltaIterator::PrepareBatch() flag. However, diff scans will need to use both SelectUpdates() and ApplyUpdates(), and it'd be a shame to have to reseek and reprepare just to use both extraction methods. As such, this patch makes it possible to prepare a batch for use in multiple delta extraction methods.
