  Modified files:
    sys/netinet          in.c in_pcb.c in_pcb.h ip_divert.c 
                         raw_ip.c tcp_subr.c udp_usrreq.c 
    usr.bin/netstat      inet.c 
  Add in_pcbinfo_init() to encapsulate basic structural setup (right now just
  the LIST_INIT).  Rename inpcbinfo->listhead to inpcbinfo->pcblisthead due
  to changes in the API (addition of markers).
  Add support for markers in the inpcbinfo->pcblisthead lists of INPCB
  structures.  Use markers in sysctl output code to iterate through these lists
  without losing its place or having to worry about structures being ripped out
  from under it.  Scrap the original two-pass code.
  Redo the sysctl INPCB output code for tcp, udp, and other protocols so we
  always output the correct number of structures (as specified in xig_count).
  Generate output for all cpus (for TCP).  This is accomplished by using
  lwkt_setcpu_self() to migrate the kernel thread to each cpu, which allows us
  to iterate the list(s) managed by that cpu without having to deal with mutexes
  or other forms of locks.  Iterations always wind up on the same cpu they began
  Redo netstat to properly iterate across as many cpu chunks as the inpcb
  sysctl's return, rather then just the first one.
