  Modified files:
    sys/kern             uipc_socket.c 
    sys/netinet          ip_input.c udp_usrreq.c 
    sys/sys              socket.h 
  Log:
  Introduce the SO_BINTIME option which takes a high-resolution timestamp
  at packet arrival.
  
  For benchmarking purposes SO_BINTIME is preferable to SO_TIMEVAL
  since it has higher resolution and lower overhead.  Simultaneous
  use of the two options is possible and they will return consistent
  timestamps.
  
  This introduces an extra test and a function call for SO_TIMEVAL, but I have
  not been able to measure that.
