AutoReporter is going away; recent versions of sphinx emit a warning like:

  /stuff/k/git/kernel/Documentation/sphinx/kerneldoc.py:125:
      RemovedInSphinx20Warning: AutodocReporter is now deprecated.
      Use sphinx.util.docutils.switch_source_input() instead.

Make the switch.  But switch_source_input() only showed up in 1.7, so we
have to do ugly version checks to keep things working in older versions.

IIUC you don't need to save the state anymore, so the above two lines
should be sufficient when using switch_source_input.

BR,
Jani.
