Cleanup docs builds and error on warnings
The docs builds throw quite a few exceptions and warnings. Most of this
is due to code that has moved around so autodoc can't import code to
document that code. Update the names for code that has moved. There were
also so small docstring indentation issues that are corrected.
In addition to fixing these issues, update the minimum version of sphinx
and set warning-is-error so that we avoid these problems in the future
by gating on making sure they don't exist.
