In some environments, where building only the manual pages and not the other documentation is desired, installing a toolchain for building DocBook-based manual pages may be burdensome, and using Asciidoctor directly may be easier, so let's add an option to build manual pages using Asciidoctor without the DocBook toolchain. We generally require Asciidoctor 1.5, but versions before 1.5.3 didn't contain proper handling of the apostrophe, which is controlled normally by the GNU_ROFF option. This option for the DocBook toolchain, as well as newer versions of Asciidoctor, makes groff output an ASCII apostrophe instead of a Unicode apostrophe in text, so as to make copy and pasting commands easier. These newer versions of Asciidoctor (1.5.3 and above) detect groff and do the right thing in all cases, so the GNU_ROFF option is obsolete in this case. We also need to update the code that tells Asciidoctor how to format our linkgit macros so that it can output proper code for man pages. Be careful to reset the font to the previous after the change. In order to do so, we must reset to the previous after each font change so the previous state at the end is the state before our inserted text, since troff only remembers one previous font. We insert \e before each font-change backslash so Asciidoctor doesn't convert them into \*(rs, the reverse solidus character, and instead leaves them as we wanted them. Additionally, we don't want to use XML-style escapes for the litdd and plus macros, so let's only use the XML-style escapes in HTML and XML and use something different for our man pages. Because Asciidoctor versions before 2.0 had a few problems with man page output, let's default this to off for now, since some common distros are still on 1.5. If users are using a more modern toolchain or don't care about the rendering issues, they can enable the option.
