LUDOC-130 install-progrIF: Updated install procedures. Also LUDOC-116,158.

Updates to Chapter 8 (Installing from RPMs), new content
in Chapter 29 (Installing from source), updates to Chapter 33
(Programming Interfaces), new content in Chapter 16 (Upgrading).
All of these chapters are interconnected by cross-references to
target text that required editing.  Since Ch 33 was being edited,
it was updated with changes unrelated to installation as well.
