sfdnsres: Cleanup service and implements some calls (#2130)
* 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: Co-Authored-By: Mary <1760003+Thog@users.noreply.github.com> Co-Authored-By: riperiperi <6294155+riperiperi@users.noreply.github.com> * Addressed gdkchan's comments * IPAddress[] to IEnumerable * Nits Co-authored-by: Mary <1760003+Thog@users.noreply.github.com> Co-authored-by: riperiperi <6294155+riperiperi@users.noreply.github.com>
