[avahi] BUG/BYDESIGN avahi_entry_group_add_service

[Stefan de Konink]

host 	The host this services is residing on. We recommend to pass NULL 
here, the daemon will than automatically insert the local host name in 
that case

It is strange:

1) Avahi doesn't allow an IP address as host
2) Ignores the host completely, and if the host is correct it will still 
export *all* (public/private) IPs. (like it was NULL)
