fail to compile with openssl-1.1.x

[A. Schulze]

Hi again,

now I get compile errors. Is openssl-1.1.xy supported?

iostream-openssl.c: In function 'openssl_iostream_verify_client_cert':
iostream-openssl.c:118:37: error: dereferencing pointer to incomplete type
   subject = X509_get_subject_name(ctx->current_cert);
                                      ^
iostream-openssl.c:127:37: error: dereferencing pointer to incomplete type
     X509_verify_cert_error_string(ctx->error), certname));
