Merge r269998 from head:
- 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.
