* 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
