Cleanup of configuration.
o Use `expr' instead of `NUM' and `ipa' instead of `IPA', so that defined symbols work everywhere. o `define' now accepts both numbers and IP addresses. o Renamed `ipa' in filters to `fipa'. Pavel, please update filters to accept define'd symbols as well.

- check incoming packets and log errors!!

- check if all protocols set proper packet priorities and TTL's.
-- replace all NUM, IPA and expr tokens by constant filter expressions
