495e6367af Add experimental support for channels.
This adds experimental::channel and experimental::concurrent_channel.
Channels may be used to send completions as messages. For example:

  // Create a channel with no buffer space.
  channel<void(error_code, size_t)> ch(ctx);

  // The call to try_send fails as there is no buffer
  // space and no waiting receive operations.
  bool ok = ch.try_send(asio::error::eof, 123);
  assert(!ok);

  // The async_send operation blocks until a receive
  // operation consumes the message.
  ch.async_send(asio::error::eof, 123,
      [](error_code ec)
      {
        // ...
      });

  // The async_receive consumes the message. Both the
  // async_send and async_receive operations complete
  // immediately.
  ch.async_receive(
      [](error_code ec, size_t n)
      {
        // ...
      });
