[PATCH v3 12/33] docs: ide: convert docs to ReST and rename to *.rst

Mauro Carvalho Chehab
2019-06-09T02:29:19Z

The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
