[RFC PATCH v1 4/6] kernel-doc: insert TODOs on kernel-doc errors

[Markus Heiser <markus.heiser@darmarit.de>]

The rstKernelDoc.py sphinx-extensions inserts '.. todo::' on
errors. With this patch sphinx.ext.todo extension [1] is activated.
This is similar to what we know from DocBook's *Oops* functionality of
the kernel-doc perl script [2].

I added this functionality (only) to the subproject, to left the main
build untouched. E.g. run::

  make SPHINXDIRS="driver-api" htmldocs

open the HTML output and scroll down to see those *Oops* (TODO) boxes.

The *Oops* in the HTML output helps authors to find rough errors and
increase the quality of the documentation. ATM there are to many
errors (false positives) and it needs some discussion. Take this as a
starting point.
