  Modified files:
    sys/netinet          in_pcb.c tcp_input.c tcp_subr.c 
  Log:
  Before dereferencing intotw() when INP_TIMEWAIT, check for inp_ppcb being
  NULL.  We currently do allow this to happen, but may want to remove that
  possibility in the future.  This case can occur when a socket is left
  open after TCP wraps up, and the timewait state is recycled.  This will
  be cleaned up in the future.
