This change adds an option to allow not using xmlto at all but instead
using just Asciidoctor to generate manual pages.  If you do nothing,
you'll continue to use xmlto as before.

The first released version is 1.5.3.

My general policy, which need not be Git's policy (but I think is
reasonable), is that I will support the previous version of Debian and
Ubuntu LTS for a year after the new one comes out.  Under that policy,
we'd wait until a year after Debian 11 (bullseye) is released.

I can make that change.  We're not using DocBook either way, with xmlto
or other tooling (e.g., a plain xsltproc), so what we have here is
accurate.
