Subject: [PATCH] doc: add texinfodocs and infodocs targets

Sphinx supports generating Texinfo sources and Info documentation,
which can be navigated easily and is convenient to search (via the
indexed nodes or anchors, for example).

This change also causes the html output to appear under its own output
sub-directory, which makes it easier to install, since it's clean from
.doctrees or other output formats.
