Almost two months ago, the warning about non-existing config file was

Tor uses these values to implement a low-rent clone of RFC 5705 (which,
in our defense, we came up with before RFC 5705 existed).  But now that
ssl_st is opaque, we need another way to get at them.

Includes documentation, with suitable warnings about not actually
using these functions.

longer visible, so we need a method to get at it.
