      Import most fixes from FFTPACK51 · c240a96f

      Most if the fixes are due to computing the lengths (and indices) for
      LENSAV.  Apparently the lengths should be log2(N) instead of log(N).
      But the fix for c1fm1f.f fixes a genuine bug in the complex fft which
      caused wrong results for non-power of 2 FFT sizes.
      Also fixed a couple of typos and incorrect return ier codes.
