64448e6a19 Add any_completion_handler<>. 
The any_completion_handler<> template can be used to type-erase
completion handlers. A typical use case is to enable separate
compilation of asynchronous operation implementations. For example:

  // Header file:

  void async_sleep_impl(
      boost::asio::any_completion_handler<void(boost::system::error_code)> handler,
      boost::asio::any_io_executor ex, std::chrono::nanoseconds duration);

  template <typename CompletionToken>
  inline auto async_sleep(boost::asio::any_io_executor ex,
      std::chrono::nanoseconds duration, CompletionToken&& token)
  {
    return boost::asio::async_initiate<CompletionToken, void(boost::system::error_code)>(
        async_sleep_impl, token, std::move(ex), duration);
  }

  // Separately compiled source file:

  void async_sleep_impl(
      boost::asio::any_completion_handler<void(boost::system::error_code)> handler,
      boost::asio::any_io_executor ex, std::chrono::nanoseconds duration)
  {
    auto timer = std::make_shared<boost::asio::steady_timer>(ex, duration);
    timer->async_wait(boost::asio::consign(std::move(handler), timer));
  }

a312a46715 Move as_tuple to the asio namespace. 
This is no longer an experimental facility. The names as_tuple and
as_tuple_t have been temporarily retained as deprecated entities under
the asio::experimental namespace, for backwards compatibility.
