Cleanup
- many_fft should be 1 for CPU execution!
- *_clock_gpu => *_clock
- dmft case for GPU (tentative)
- useless preprocessing removed
- rhoaux replaced by rho%of_r. Something similar should be done systematically for all charge-density variables: they should always be on GPU, be copied to/from CPU only when writing/reading
