Merge branch 'install' into docs-next

Mauro says:

Sphinx installation is not trivial, as not all versions are supported,
and it requires a lot of stuff for math, images and PDF/LaTeX output
to work.

So, add a script that checks if everything is fine, providing
distro-specific hints about what's needed for it to work.
