* ext/syck/rubyext.c: sorry, I reverted my "should set newly

  allocated memory instead of RString's internal storage" stuff.
  node allocated in rubyext.c seems to be freed by rb_syck_free_node
  not syck_free_node, and it won't free data.str->ptr and type_id.

 (I still think this is unsafe because RString(foo)->ptr becomes
  dangling pointer when RString is modified or freed, but anyway
  I misunderstood, so go back to original code for now)
