Futures vs Threads benchmark

Compare asynchronous tokio + futures with blocking std::net + std::thread.

The benchmark is a multiecho server: client connects to the server, sends "Hello, World!" and the server broadcasts the message to all previously connected clients. Thus, n clients will send and receive n^2 messages in total.

• src/threads.rs is implementation which spawns a thread per each client.
• src/fut.rs is a single threaded future based implementation.
• src/bench.rs simulated 3000 clients.
