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.

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.

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.

ec11cfdf75 avfilter/vf_delogo: Use AVPixFmtDescriptor.nb_components 
Relying on AVPixFmtDescriptor.nb_components is cleaner and faster than
checking data and linesize for every possible plane.

89bbf01978 lavfi/af_amix: fix memory leak 
Recent commits 6aaac24d72 and
3835554bf8 made progress towards cleaning
up usage of the formats API, and in particular fixed possible NULL pointer
dereferences.

This commit addresses the issue of possible resource leaks when some intermediate
call fails.

Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation
of malloc/realloc failures.

Fixes: CID 1250334.
