Take the chance to update some includes using files available in that
subdir to have them ina more uniform way.

The behaviour of a mismatched pair of allocation and deallocation is undefined
Also fixes a memory leak if malloc fails (which stops the application anyway)

Introduce polyphase channelizer (Rx) and synthesis (Tx) filterbanks,
which serve as the signal processing backend for multi-carrier GSM.
Fast Fourier Transform (FFT) is used internally. FFTW is added as
a new build dependency.
