SSL: fixed segfault on renegotiation (ticket #1646). In e3ba4026c02d (1.15.4) nginx own renegotiation checks were disabled if SSL_OP_NO_RENEGOTIATION is available. But since SSL_OP_NO_RENEGOTIATION is only set on a connection, not in an SSL context, SSL_clear_option() removed it as long as a matching virtual server was found. This resulted in a segmentation fault similar to the one fixed in a6902a941279 (1.9.8), affecting nginx built with OpenSSL 1.1.0h or higher. To fix this, SSL_OP_NO_RENEGOTIATION is now explicitly set in ngx_http_ssl_servername() after adjusting options. Additionally, instead of c->ssl->renegotiation we now check c->ssl->handshaked, which seems to be a more correct flag to test, and will prevent the segmentation fault from happening even if SSL_OP_NO_RENEGOTIATION is not working.
