Remove sorting from tabular_writer

[jsiirola]

Fixes # .

Supersedes #3578.

Summary/Motivation:

This removes all sorting from the tabular_writer, and prints out the data in the order in which the data iterator provides it. Control for sorting int pprint() is now exposed through the pprint() API. This makes the tabular_writer simpler / more generic and more usable in other contexts.

This is currently backwards compatible with the existing pprint() infrastructure and will produce the same output. A subsequent PR will rework the pprint() design so that components are output in "ordered" (and not "sorted") order, as well as other changes that might break the output.

Changes proposed in this PR:

• remove sorting from tabular_writer
• update the pprint() private API so that sorting can be controlled by an optional argument to pprint()
