Lists are ready for migration to ipsets

New functions: ipset_start() and ipset_stop(),
where all ipset management will be performed.

ipset creation is slow, restore from dump is quicker.
Dump creation is done only for the first run. Next run will
restore from this dump. If you change list, delete corresponding
dump and re-run.

In debug mode all ipset cmds will be dumped to stdout anyways.
