Doc: update remaining tables of functions/operators for new layout.

This converts the contrib documentation to the new style, and mops up
a couple of function tables that were outside chapter 9 in the main
docs.

A few contrib modules choose not to present their functions in the
standard tabular format.  There might be room to rethink those decisions
now that the standard format is more friendly to verbose descriptions.
But I have not undertaken to do that here; I just converted existing
tables.
