* array.c (rb_ary_and): should not push frozen key string.

* array.c (rb_ary_or): ditto.

* eval.c (rb_thread_schedule): should save context before raising
  deadlock, saved context for current thread might be obsolete.

* time.c (make_time_t): non DST timezone shift supported (hopefully).

* signal.c: SIGINFO added.

* eval.c (rb_ensure): should not SEGV when prot_tag is NULL.
