[fdo-internals] Counting rows in managed IFeatureReader

[Jason Birch]

Are there any concerns about the number of records changing between the
first SelectAggregates and the Select, or are all providers
transactional across a single session?

The 1st select should be a selectaggregate call using function Count()
where it is available.  This will be optimized for most provider, will
avoid a full table scan and will limit the number of trip to the server.
The 2nd is to process those rows as needed.
