[PATCH i-g-t 0/3] Switch the FFT library to meow_fft

[Kamil Konieczny <kamil.konieczny@linux.intel.com>]

This is a resend of Ryszard Knop series from here:
https://patchwork.freedesktop.org/series/107093/

with a rebase and small cleanup in lib/igt_audio.c
and adding a SPDX licence to meow_fft files.

Old series description:

   In Chamelium tests, FFT is used to compare the transmitted vs received
signal. Currently this is done with the GNU GSL library.

GSL is available under the GPL license which is incompatible with MIT,
as noted in #38. Switch to meow_fft, licensed under 0-clause BSD.
