A Sphinx domain is a collection of directive and role extensions meant
to facilitate the documentation of a specific language. For instance,
Sphinx ships with "python" and "cpp" domains. This patch introduces a
stub for the "qapi" language domain.

Please see https://www.sphinx-doc.org/en/master/usage/domains/index.html
for more information.

This stub doesn't really do anything yet, we'll get to it brick-by-brick
in the forthcoming commits to keep the series breezy and the git history
informative.
