In some cases it is required to change openssl options running tcltls. There may be more and other options as I need and describe here.

E.g. running tclhttpd with tcltls needs openssl to change client to server cipher order to pass SSL Labs's 'SSL Server Rating Guide' (version 2009q from 2020-01-30) as grade A.

I don't know a better way as to add SSL_OP_CIPHER_SERVER_PREFERENCE to tcl.c but would prefer to have an option in ::tls::init

tls.c:1215    SSL_CTX_set_options( ctx, SSL_OP_ALL | SSL_OP_CIPHER_SERVER_PREFERENCE );	/* all SSL bug workarounds */
