  Modified files:
    lib/libthr/thread    thr_cancel.c 
  Log:
  o Make the setting/checking of cancel state atomic with
    respect to other threads and signal handlers by moving to
    the _thread_critical_enter/exit functions.
  
  o Introduce an static function, testcancel(), that is used by
    the other functions in this module. This allows it to make
    locking assumptions that the top-level functions can't.
  
  o Rework the code flow a bit to reduce indentation levels.
