Title: Add Sphinx coverage testing to the coverage_doctest.py tool

This checks if the function is imported into Sphinx. This works by checking
the source from the Sphinx viewcode extension.

This fixes issue 2896.

I still need to add verbose output, and I also need to add some error checking
if the Sphinx docs haven't been built.
