Can you provide a motivating use-case for this accessor?  In
verification callbacks this lets you peek not only at the current
certificate, but also its issuer, but setting this has no useful
side-effects.

I've not looked at the CRL check code closely enough to know whether
there's a use-case there, but at first glance it looks unlikely.
