Bug 568723 – g_buffered_input_stream_fill_async doesn't take count == -1

        Bug 568723 – g_buffered_input_stream_fill_async doesn't take count == -1

        * gbufferedinputstream.c (g_buffered_input_stream_fill_async,
        g_buffered_input_stream_fill): check for count < -1 instead of count <
        0 and copy modified check to non-async version for consistency.
        document the "count = -1" API.
