Doug Hellmann 97986ff795 invoke sphinx directly instead of through pbr ... The pbr feature for invoking sphinx doesn't let us treat warnings as errors because of a bug in pbr. Switch to invoking sphinx directly, including removing the setup.cfg instructions for sphinx, so we can use the flag to treat warnings as errors. Doing this also requires fixing a few existing warnings, so those changes are included in this patch.
