Code modernization: src/n*, src/o* (#6280)
* Code modernization: src/n*, src/o* * empty function * default constructor/destructor * for range-based loops * use emplace_back instead of push_back * remove unused IWritableNodeDefManager::clone() * C++ STL header style * Pointer constness in some functions
