It is not obvious from "It does not take ownership of |buf|" whether the
function makes a copy or not. It does not make a copy (maybe it
should...), so callers are obligated to manage their lifetimes.

OpenSSL synchronizes bio->next_bio and ssl->rbio with a variety of
callbacks, so BIO_copy_next_retry worked. We do not, so attempting to
flush the BIO crashed.
The SSL BIO is a compatibility hack and intentionally much more limited,
so start by just copying things from the right BIO directly. Add a basic
unit test for SSL BIOs. If we need to, we can implement a more complex
synchronization later.
Additionally reject reconfiguring an SSL BIO because that will leak the
object right now.
