syncbase/store: store in-flight mutations of a transcation in a ptrie

The reason to do it is to make fast snapshots of in-flight mutations.
Before this change, every scan inside a transaction created a copy of
all in-flight mutations and sorted them by key. This is bad for queries
as a query might do multiple scans inside a transaction.
