Message is a C++ type with a simple ownership model appropriate for std::unique_ptr. This CL applies the following changes: 1. All uses of "new Message(...)" are replaced with "Message::New(...)", which is effectively "std::make_unique<Message>(...)". (The latter was only added in C++14, but Dart still compiles in C++11 mode.) 2. All owning Message* are replaced with std::unique_ptr<Message>. The notable exception is MessageQueue, which still uses raw Message* internally to simplify the linked list handling. 3. All "delete message;" statements are removed. 4. Uses of "NULL" replaced with "nullptr" as necessary.
