Using -t on an input already have surprising results.
Furthermore, using it on an input or an output makes
a real difference if there are speed-altering filters.

Implementing -t for inputs will probably result in some
behavour changes.

The warning silenced was: libavfilter/af_amerge.c:144:29: warning: conversion specifies type 'long long' but the argument has type 'int' [-Wformat]

The warning was introduced after FF_API_SAMPLERATE64 removal.

The function call was a mess to handle, and memcpy cannot make
the assumptions we do in the new code.

while others lack this header entirely.  Including it conditionally

Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.

This adds a fallback for cbrtf() using powf(x, 1/3).  Since
powf() with a non-integer exponent requires a non-negative
base, special handling of negative inputs is needed.
