Queries the stream information asynchronously.
When the operation is finished callback will be called.
You can then call g_file_input_stream_query_info_finish()
to get the result of the operation.
For the synchronous version of this function,
see g_file_input_stream_query_info().
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be set
