The function make-ssl-ctx first calls ensure-ssl, and returns a foreign pointer of type ssl-ctx-pointer.
If the value of ssl-ctx is t, :default, :v2, :v3, :v23 or :tls-v1, make-ssl-ctx creates a SSL_CTX object and returns a pointer to it.
The value of ssl-ctx can also be a foreign pointer of type ssl-ctx-pointer, in which case it is simply returned. If ssl-ctx is a foreign pointer of type ssl-pointer, then make-ssl-ctx signals an error.
The meaning of the keyword arguments ssl-ctx and ssl-side is as described for socket-stream. The default value of ssl-ctx is t and the default value of ssl-side is :server.
