manual: Split out the topics of converted manpages into separate files and generate ditamap files for each manpage to avoid needing to hardcode anything in UserManual.xml. This means that the topics inside a manpage can be supressed from the toc, but otoh, they get numbered (with 4.x). The per-topic files are named by refentry/refsect1/refsect2 @id and are currently not cleaned up by 'kmk clean'. bugref:10302
