Oracle Database 12c new feature: the row limit clause

An age old problem with SQL is pagination through a row set. You want to display rows one page at a time, in some sort of order. The issue is architectural: SQL is a set oriented language. It deals with rows as a group, not individually, making it impossible to paginate through a set because that would require navigation from row to row. There are work arounds, there are potential programming bugs, and there is a Database 12c New Feature: the row limit clause. All demonstrations below are done with 12c final beta, release 12.1.0.1.0. Below is the old and the new way, with a bit of reverse engineering.
