DOC: Deep revision of documentation building

This PR follows up on nipy#3119 (merge that one first for a clean diff, or
diff against ``oesteban:maint/dedup-apigen-code``).

In practice, this PR fixes several broken points of our documentation
(e.g., the workflows list was empty and now it has been updated,
changelog not rendered, API of pure python code not rendered by the
Nipype API parser was missing, etc.).

CHANGES
-------

* Replaced the ``numpydoc`` sphinx extension with
``sphinxcontrib-napoleon``.
* Removed autosummary sphinx extension, required by numpydoc
* Cleared up ``docs/sphinxext/*``, as nothing is now used from there
* Use current sphinx-apidoc/autodoc/autosummary
* Removed the modref generation tooling, as it is not necessary anymore
  after re-enabling apidoc.
* Cut building warnings down to 321 - just those we incur because our
  API generator. This required some fixes of some docstrings.
  Beyond those corresponding to the Nipype API generator, only missing
  links remain as warnings (for sections in the navbar).
* Updated changelogs to be reStructuredText.
