 *	- new API and handling of conntrack/nat helpers
 *	- now capable of multiple expectations for one master
 * 16 Jul 2002: Harald Welte <laforge@gnumonks.org>
 *	- add usage/reference counts to ip_conntrack_expect
 *	- export ip_conntrack[_expect]_{find_get,put} functions
 * 16 Dec 2003: Yasuyuki Kozakai @USAGI <yasuyuki.kozakai@toshiba.co.jp>
 *	- generalize L3 protocol denendent part.

 *	- add support various size of conntrack structures.
 * 26 Jan 2006: Harald Welte <laforge@netfilter.org>
 * 	- restructure nf_conn (introduce nf_conn_help)
 * 	- redesign 'features' how they were originally intended
 * 26 Feb 2006: Pablo Neira Ayuso <pablo@eurodev.net>
