  Log:
    * parse.y: change Symbol <-> ID relationship to avoid
      exposing IDs from collectable symbols.
      [Bug #10014]
      Now, rb_check_id() returns 0 if corresponding symbol is
      pinned dynamic symbol.
      There is remaining intern_cstr_without_pindown(), it can return
      IDs from collectable symbols. We must be careful to use it
      (only used in parse.y).  I think it should be removed if
      it does not have impact for performance.
    * parse.y:
      add:
      * STATIC_SYM2ID()
      * STATIC_ID2SYM()
      rename:
      * rb_pin_dynamic_symbol() -> dsymbol_pindown()
    * internal.h:
      remove:
      * rb_check_id_without_pindown()
      * rb_sym2id_without_pindown()
      add:
      * rb_check_symbol()
      * rb_check_symbol_cstr()
    * load.c: use rb_check_id() or rb_check_id_cstr().
    * object.c: ditto.
    * struct.c: ditto.
    * thread.c: ditto.
    * vm_method.c: ditto.
    * string.c (sym_find): use only rb_check_symbol().
    * sprintf.c (rb_str_format): use rb_check_symbol_cstr().
