[PATCH v4 00/12] doc: cleanup old cruft and asciidoctor revamp

This patch series gets rid of old unnecessary workarounds and convoluted solutions.

Additionally it cleanups the asciidoctor-specific code so it ends up much more simpler.

This goes on top of my other cleanup patches [1] (already in seen), but conflicts with bc/doc-asciidoctor-to-man-wo-xmlto which in my opinion should be dropped since I have better proposal.

No changes since last version.
