HTTP/3: reference h3c directly from ngx_http_connection_t. Previously, an ngx_http_v3_connection_t object was created for HTTP/3 and then assinged to c->data instead of the generic ngx_http_connection_t object. Now a direct reference is added to ngx_http_connection_t, which is less confusing and does not require a flag for http3.
