readUptoAsync
The asynchronous version of g_data_input_stream_read_upto(). It is an error to have two outstanding calls to this function.
In contrast to g_data_input_stream_read_until(), this function does not consume the stop character. You have to use g_data_input_stream_read_byte() to get it before calling g_data_input_stream_read_upto() again.
Note that @stop_chars may contain '\0' if @stop_chars_len is specified.
When the operation is finished, @callback will be called. You can then call g_data_input_stream_read_upto_finish() to get the result of the operation.
