I've implemented this now by adding a counter for the accumulated error and
adding an additional sample to every interval when it overflows (i.e. >=
GST_SECOND).

        * gst/spectrum/gstspectrum.c: (gst_spectrum_reset_state),
        (gst_spectrum_transform_ip):
        * gst/spectrum/gstspectrum.h:
        Implement a simple compensation algorithm for rounding errors.
        This makes sure that a spectrum message is posted on the bus
        every interval nanoseconds. Fixes bug #567955.
