[PATCH v2 00/11] doc: asciidoctor: direct man page creation and fixes

This patch series enables direct man page creation with asciidoctor, but in addition tries to minimize the difference with asciidoc+docbook.

I fixed as many issues as I could, and now the doc-diff looks very sensible. I could not find any major issues, however, some minor ones still remain.

On the other hand the asciidoc method has issues as well, so it's not clear which method is superior at this point; both have advantages and disadvantages.

At the very least the man pages with pure asciidoctor should be quite usable now.

This series builds on top of my previous cleanups [1].
