* sfdnsres: Cleanup service and implements some calls

This PR is a big cleanup to our current implementation of `sfdnsres` service.
Additionnaly to that, some calls and fix have been done by @Thog (PRd with approval, thanks to her).
- Implementation of `GetAddrInfoRequest` (Fixes #637).
- Partial implementation of `GetHostByNameRequestWithOptions`, `GetHostByAddrRequestWithOptions` and `GetAddrInfoRequestWithOptions` (Fixes #642, Fixes #1233).

A DNS Blacklist have been done by @riperiperi (which is currently used in LDN build, then that reduces code differences between the LDN build and master.

Now a lot of games are playable or are blocked to the menu because it needs online service:
