document the -S command line option to dump capture statistics
Close PCAPs after dumper_close() to have statistics still available during dumper_close(). Otherwise we get a segfault on shutdown.
Count every packet which is sent to output(), not only the normal ones.
Add -W feature: allow to specify a suffix for the pcap dump file, e. g.: '.pcap'
Fix compiler warning
New option -C: limit/rotate capture after a certain amount of bytes
