[PATCH 21/31] flexible-arrays.txt: standardize document format

[Mauro Carvalho Chehab]

Each text file under Documentation follows a different
format. Some doesn't even have titles!

Change its representation to follow the adopted standard,
using ReST markups for it to be parseable by Sphinx:

- use :Author: and :Updated: markups;
- use proper markup for the document title;
- mark the literal-blocks.
