Hello Mike Percy, David Ribeiro Alves, Kudu Jenkins, Grant Henke, Todd Lipcon,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).
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.
