       The SSL_get0_connection() function, when called on a QUIC stream SSL object, returns the QUIC connection
       SSL object which the QUIC stream SSL object belongs to.

       When called on a QUIC connection SSL object, it returns the same object.

       When called on a non-QUIC object, it returns the same object it was passed.

       SSL_is_connection() returns 1 for QUIC connection SSL objects and for non-QUIC SSL objects, but returns 0
       for QUIC stream SSL objects.

       These functions were added in OpenSSL 3.2.

       SSL_get0_connection, SSL_is_connection - get a QUIC connection SSL object from a QUIC stream SSL object

SSL_get0_connection() returns the QUIC connection SSL object (for a QUIC stream SSL object) and otherwise
       returns the same SSL object passed. It always returns non-NULL.

       SSL_is_connection() returns 1 if the SSL object is not a QUIC stream SSL object and 0 otherwise.
