documentation: Re-write of dev-manual setup chapter
Fixes [YOCTO #11630]
The chapter on setting up YP has been completely re-written to
move towards a "how-to" manual. This involved touching every
aspect of the chapter. All subsections now have procedures
surrounding set up stuff. There are some development sections that
still need fleshed out.
Many, many links and references in other chapters were affected.
These have been fixed.
A couple style-sheet (*.css) files were also updated to support the
"writernotes" style, which renders paragraph text in red.

220 | For traditional kernel development using the Yocto | ||
