  Log:
  MFC part of if_bge.c revision 1.41: atomically load and clear the
  status block.  This makes the bge devices work much better when
  interrupts are shared.
  
  This change entails bringing in the atomic_readandclear_* functions
  from -current.  RELENG_4 already had the equivalent loadandclear
  function for the i386, but it did not exist for the alpha.
