        Add libgstfft, a FFT library based on Kiss FFT which is
        BSD licensed. Supported sample formats are int16, int32,
        float and double. For those formats a real FFT and IFFT
        can be done, different windowing functions can be applied
        and functions for extracting the magnitude and phase exist.
        Fixes #468619.

        * tests/check/libs/fft.c: (GST_START_TEST), (fft_suite), (main):
        Add unit tests for libgstfft, currently only testing the FFT.
        Unit tests for IFFT will follow soon.
