Doc: re-re-revise markup for tables of functions.

Make the markup a bit less ad-hoc.  A function-table cell now contains
several  units, and we label the ones that contain function
signatures with role="func_signature".  The CSS or FO stylesheets then
key off of that to decide how to set the indentation.  A very useful
win from this approach is that we can have more than one signature
entry per table cell, simplifying the documentation of closely-related
operators and functions.

This patch mostly just replaces the markup in the tables I converted so
far.  But I did alter a couple of places where multiple signatures were
helpful.
