Dart_NewNativePort creates a port associated with a C handler function. When messages come in on this port, they are forwarded to the C function for processing. To support this, refactored PortMap so that it operates on a new MessageHandler type instead of directly on Isolates. For now, native ports have a dedicated single thread. Eventually we will back native ports (and possibly Isolates as well) by a shared thread pool.
