The current TOC organization is not really following Sphinx best
practices and is resulting in a jumble of articles showing up in the
sidebar.
This change primarily organizes existing articles into three major
sections:
* Introduction
- Contains system requirements, architecture & design, installation,
basic setup
* Basics
- Covers basic commands, concepts, and some random things that don't
fit elsewhere
* Protocols
- Contains all protocol documentation, and other miscellaneous daemon
docs such as those on Zebra, watchfrr, mgmtd, etc.
The appendix has been left as is, but the TOC now has a caption which
has the effect of adding a section separator in the nav sidebar.
In order to make the new structure make sense:
* Some content has been lifted up from the "Overview" page into the
index page
* Most content has been pushed down from the "Overview" page into the
"About" page (new)
* BFD's page is now titled "BFD" for consistencty; it was the only one
that had the full protocol name written out in the title
And a couple drivebys:
* BFD's intro description paragraph was rewritten to make more sense
* Old language stating that we publish platform packages on the Github
releases page was removed
* References to source building instructions were consolidated into that
section
