Reads data into @stream's buffer asynchronously, up to @count size.
@io_priority can be used to prioritize reads. For the synchronous
version of this function, see g_buffered_input_stream_fill().
If @count is -1 then the attempted read size is equal to the number
of bytes that are required to fill the buffer.
