Revive mlfk_ipl here. This version is slightly changed from
the old one: an unnecessary define (KLD_MODULE) has been deleted and the initialisation of the module is done after domaininit was called to be sure inet is running. Some slight changed were made to ip_auth.c and ip_state.c in order to assure including of sys/systm.h in case we make a kld Make sure ip_fil does nmot include osreldate in kernel mode Remove mlfk_ipl.c from here: no sources allowed in these directories!
