• Count global pf(4) statistics in counter(9).
• Do not count global number of states and of src_nodes, use uma_zone_get_cur() to obtain values.
• Struct pf_status becomes merely an ioctl API structure, and moves to netpfil/pf/pf.h with its constants.
• V_pf_status is now of type struct pf_kstatus.
