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.
