  Modified files:
    sys/contrib/pf/net   if_pfsync.c pf_norm.c 
    sys/modules/pf       Makefile 
  Log:
  Get rid of the RANDOM_IP_ID option and make it a sysctl.  NetBSD
  have already done this, so I have styled the patch on their work:
  
          1) introduce a ip_newid() static inline function that checks
          the sysctl and then decides if it should return a sequential
          or random IP ID.
  
          2) named the sysctl net.inet.ip.random_id
  
          3) IPv6 flow IDs and fragment IDs are now always random.
          Flow IDs and frag IDs are significantly less common in the
          IPv6 world (ie. rarely generated per-packet), so there should
          be smaller performance concerns.
  
  The sysctl defaults to 0 (sequential IP IDs).
