groff online manuals updated for 1.23.0 release

[G. Branden Robinson]

Hi folks,

I've updated the groff home page.  Yesterday, to reflect the release;
today, to update the online copies of our Texinfo manual and to add the
collected groff man pages.

You can have a look at:

https://www.gnu.org/software/groff/manual/

The groff home page is managed in CVS; dealing with CVS consistently
reminds me how much more pleasant Git is to work with.  Here's a
condensed digest of changes.

---
groff online manual: Update and revamp.

* Do less by hand.
  - Add Makefile.
  - Create index.html from index.html.in.
  - Get file sizes from system.

* Drop PostScript version of manual; groff 1.23.0 doesn't generate it.

* Rename "groff.html_node.tar.gz" to "groff.html.node.tar.gz" to match
  current practice in the groff build.

* Replace "groff.texi.tar.gz" with "groff.texi.gz"; there's no point
  having a single-file tape archive.

* Provide our Texinfo in source form as well (plain and compressed).

* Update descriptions of documentation files.  Most importantly,
  describe plain texi version of our Texinfo manual as encoded in "ISO
  Latin-1" instead of "ASCII", which was incorrect.
