ddns-scripts: rollup to version 2.5.0-1

- add -V / --version parameter to show version information
- new option lookup_host as host to use by nslookup/host to validate IP address changes, to be separate from [DOMAIN] parameter which produces a lot of questions in the forum and on multi-host updates
- new option param_enc for optional usage inside update_url [PARAMENC] (will be send urlencoded)
- new option param_opt for optional usage inside update_url [PARAMOPT]
- new service strato.de (IPv4 only) requested by ludwig.jaffe@
- new service variomedia.de (IPv4 & IPv6) requested by Wolfgang Oertl #1884
- rewritten function get_service_data to read services/service_ipv6 file
- allow 3rd parameter inside services/service_ipv6 file - here should be the answer of the ddns provider on success. If parameter is set, it's checked by ddns-scripts and report errors to logfile/syslog if failed and retry
- updated tld_names.dat
