[PATCH 1/5] support: don't pass to set_search_path a big struct by value

[Florian Weimer]

* Konstantin Kharlamov:

>  /* Copy the search path from CONFIG.search to the _res object.  */
>  static void
> -set_search_path (struct resolv_redirect_config config)
> +set_search_path (const struct resolv_redirect_config* config)

This static function is called once and therefore inlined, so the
change does not matter.
