    bpo-37390: Add audit event table to documentations (GH-14406)

    Also updates some (unreleased) event names to be consistent with the others.

breaks PDF builds.

Reproductible using:

    (cd Doc; sphinx-build -b latex -d build/doctrees -D latex_elements.papersize=a4 -D latex_engine=xelatex -D latex_elements.inputenc= -D latex_elements.fontenc=\\\\usepackage{xeCJK} -Ea -A daily=1 -A switchers=1  . build/latex)

The exception raised is "NoUri", I patched sphinx [1] to add a few info, so it is a "sphinx.errors.NoUri: c-api/code".

Guess we need a real Sphinx expert to help out here. 

Somehow we need to get explicit backlinks, but I couldn't figure out how to resolve them normally through an extension. If we can do that, this will probably go away.

Looks like a failure during library.pdf, from why we try to link to c-api.

In the sphinx latex builder:

    if docname not in self.docnames:
        raise NoUri

in self.docnames during the library build, we're only having library/* links. So c-api/code is obviously not in it.

Guessing we still need to fix this...

Julien - does this exception get raised through Doc/tools/extensions/pyspecific.py? At the get_relative_uri() call (line 573) perhaps?

If so, it seems like we could just handle it there and leave out any links that aren't in the doc.
