Release ownership of the underlying native socket.
native_handle_type release( asio::error_code & ec);
            This function causes all outstanding asynchronous connect, send and receive
            operations to finish immediately, and the handlers for cancelled operations
            will be passed the asio::error::operation_aborted
            error. Ownership of the native socket is then transferred to the caller.
          
Set to indicate what error occurred, if any.
            This function is unsupported on Windows versions prior to Windows 8.1,
            and will fail with asio::error::operation_not_supported
            on these platforms.
