[PATCH RFC 0/2] docs: Deal with some Sphinx deprecation warnings

[Jonathan Corbet]

The Sphinx folks are deprecating some interfaces in the upcoming 2.0
release; one immediate result of that is a bunch of warnings that show up
when building with 1.8.  These two patches make those warnings go away,
but at a cost:

 - It introduces a couple of Sphinx version checks, which are always
   ugly, but the alternative would be to stop supporting versions
   before 1.7.  For now, I think we can carry that cruft.

 - The second patch causes the build to fail horribly on newer
   Sphinx installations.  The change to switch_source_input() seems
   to make the parser much more finicky, increasing warnings and
   eventually failing the build altogether.  In particular, it will
   scream about problems in .rst files that are not included in the
   TOC tree at all.  The complaints appear to be legitimate, but it's
   a bunch of stuff to clean up.

I've tested these with 1.4 and 1.8, but not various versions in between.
