GH646: Update help for s_server command.
* added missing help option messages
* ecdh_single option is removed as it is a no-op and not an option
supported in earlier versions
* ssl_ctx_security_debug() was invoked before ctx check for NULL
* trusted_first option can be removed, as it is always enabled in 1.1.
But not removed the option, require confirmation.
