* error.c (exit_initialize): add SystemExit#initialize to set

  instance variable status.  (ruby-bugs-ja:PR#362)
  Now accepts status as optional first argument.

* eval.c (error_handle): now SystemExit have status always.

* eval.c (system_exit): just instantiate SystemExit without raise.

* eval.c (rb_thread_start_0): initialize SystemExit properly.
