Summary: 1. Move disOwnNativeHandle() function from RocksDB to RocksObject to allow other RocksObject to use disOwnNativeHandle() when its ownership of native handle has been transferred. 2. RocksObject now has an abstract implementation of dispose(), which does the following two things. First, it checks whether both isOwningNativeHandle() and isInitialized() return true. If so, it will call the protected abstract function dispose0(), which all the subclasses of RocksObject should implement. Second, it sets nativeHandle_ = 0. This redesign ensure all subclasses of RocksObject have the same dispose behavior. 3. All subclasses of RocksObject now should implement dispose0() instead of dispose(), and dispose0() will be called only when isInitialized() returns true.
