o Created changelog file
o Deleted libctnetlink.h and libnfnetlink.h from the include/ dir. o Added support for version (-V) and help (-h) o Added event mask based support o Added GPLv2 headers o Use fprintf instead of printf o Defined print_tuple and print_proto output interfaces o ctnl_[get|del]_conntrack handles return value from kernel via msgerr o Added support for conntrack table flushing o Added test case file (test.sh) o Improve dump output o Autoconf stuff for conntrack + some pablo's modifications. o Fixed packet counters formatting (use %llu instead of %lu)
