mdns: update probe conflict function to provide service in conflict

Browse Source 
- Send service slot index to the mdns result function. In case of conflict, the user
  will have to remove the service or rename it.
- Break after hostname conflict in order to managed it first, and managed service name
  conflict after.
- Provide a function to get the TXT userdata for a service (allowing app to match with
  its own data).
