Here is a patch that does roughly that. I'm not entirely happy with the
old 'Auto-reverting non-buffer files' section, whose node name was just
'Autorevert'. I would have preferred it as a subsection to the new
auto-revert section, along with its existing two subsections, but since
its place isn't the same in the on-line and printed manuals, that
seemed technically tricky without duplicating a lot of text.

Subject: [PATCH] Reorganise (auto-)revert nodes in the manual
The amount of information on auto-revert has grown to deserve a
section of its own (bug#35418).
* doc/emacs/files.texi:
* doc/emacs/arevert-xtra.texi:
* doc/emacs/buffers.texi:
* doc/emacs/emacs.texi:
Rename node 'Autorevert' to 'Non-file buffers'.
Add node 'Auto-revert' and move general information on that topic there.
Shuffle text in that node into a rough least-to-most specific order.
