 * sd-resolve:
   - make sure event loop integration works similar to event loop integration in other libs
   - maybe drop _free() call, introduce _unref() instead
-  - sd_resolve_freeanswer() is probably pointless, we don't define such a function for any other return values, but expect people to call free directly
   - maybe simplify function calls that take a sd_resolve_query object, to not also require the matching sd_resolve?
   - maybe drop the "n_proc" parameter to sd_resolve_new()?
   - change all functions to return "int" and negative errno errors
