docparse: Generate html and pdf using asciidoc{,tor}

Rewrite testinfo.pl to generate *.txt pages in asciidoc format which is
then regenerated to html (and pdf if enabled) using asciidoc,{tor}.

Replace getting Linux kernel git commit messages from local git
repository (needed after having all tests in single page, because API
has access limits; it's also better to generate everything once thus
don't depend on network connection).
