o Renamed nfct_[set|unset]_callback to nfct_[register|unregister]_callback
o Added some very brief comments to libnetfilter_conntrack.h o Implemented the conntrack printers API nfct_sprintf_* o Now nfct_default_conntrack_display display the classical /proc output, and nfct_default_conntrack_display the classical + conntrack ids o Use nfnl_talk if there's no data expected from kernel space to be processed, that is the case of nfct_[get|delete]_conntrack o Added some missing memset's zeroing o Code simplification: killed some char *buf where struct nfnlhdr is enough o Killed protocol handler destructors (fini) and nfct_unregister_proto: The library is unloaded if something goes wrong (different library versions), the modules never gets inserted in the proto_list. Fixes a segfault. o Bumped version to 0.2.0
