The peer certificate chain is not necessarily available after reusing
a session, in which case a NULL pointer is returned.
If the session is resumed peers do not send certificates so a NULL pointer
is returned by these functions. Applications can call SSL_session_reused()

The reference count of each certificate in the returned STACK_OF(X509) object
is not incremented and the returned stack may be invalidated by renegotiation.
