9dba3f8f09 lavfi/af_sofalizer: remove exp2 and replace clz by ff_clz 
ff_clz is faster, and uses an intrinsic (at the moment on GCC). exp2 is
a wasteful function for a simple integer exponentiation.

Untested.

63702014fa lavfi/af_anequalizer: remove cabs, cexp dependencies 
Replaces by real arithmetic. Tested the validity of these transformations separately.
Numerical differences are ~1e-15, and should not matter: it is not even
clear which is more precise mathematically.

4020787b5b avfilter/avf_showspectrum: make colors for log scale more user friendly 
Previosly output was almost useless because background noise, due to
windowing function picked and which is not actually present in audio,
had too much brightness.
Now output of sine wave matches more with SoX.

520a5d33f0 lavfi/af_aemphasis: remove unnecessary complex number usage 
complex is not available on all platforms. Furthermore, it is trivial to
rewrite complex number expressions to real arithmetic, and in fact
sometimes advantageous for performance reasons: by wrapping as a complex,
one forces a particular Cartesian representation that is not necessarily optimal for the purpose.

Configure dependencies also removed, and aemphasis is now available across
all platforms.
