SSL: handled SSL_CTX_set_cert_cb() callback yielding.
OpenSSL 1.0.2+ introduces SSL_CTX_set_cert_cb() to allow custom
callbacks to serve the SSL certificiates and private keys dynamically
and lazily. The callbacks may yield for nonblocking I/O or sleeping.
Here we added support for such usage in NGINX 3rd-party modules
(like ngx_lua) in NGINX's event handlers for downstream SSL
connections.
