Undocumented 3.13 C API

The following public C API is new in 3.13 (beta 1, relative to 3.12), and as of this writing it looks either

• undocumented, or
• documented incorrectly. See the docs search page for what Sphinx thinks the type and fully-quilfied name of the symbol are; it should be a C entry without extraneous namespaces. (The details tend to matter for search, URLs, and Intersphinx links.)
