For better compatibility with mod_nss:

* modules/ssl/ssl_engine_config.c (ssl_config_server_new): Default
  sc->enabled to UNSET.

* modules/ssl/ssl_engine_init.c (ssl_init_Module): Only override
  sc->enabled based on the protocol iff sc->enabled is UNSET; allows
  "SSLEngine off" to override the Listen-based default.
