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 gio.buffered_input_stream.BufferedInputStream.fill.
If count is -1 then the attempted read size is equal to the number
of bytes that are required to fill the buffer.
