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.

1655788712 lavfi: make request_frame() non-recursive.
Instead of calling the input filter request_frame() method,
ff_request_frame() now marks the link and returns immediately.

39a09e995d lavfi: deprecate avfilter_link_set_closed().

cc37b31ad3 lavfi/vf_colorchannelmixer: replace round by lrint
lrint is faster here on -ftree-vectorize with GCC. This is likely simply
an artifact of GCC's rather terrible auto-vectorizer, since as per the
instruction set manuals cvtsd2si and cvttsd2si (or their vector equivalents)
have identical cycle timings.

Anyway, regardless of above, lrint is superior to round accuracy wise.

Safety guaranteed as long int has at least 32 bits.
