/**
* Parse and evaluate an expression.
* Note, this is significantly slower than av_expr_eval().
*
* @param res a pointer to a double where is put the result value of
* the expression, or NAN in case of error
* @param s expression as a zero terminated string, for example "1+2^3+5*5+sin(2/3)"
* @param const_names NULL terminated array of zero terminated strings of constant identifiers, for example {"PI", "E", 0}
* @param const_values a zero terminated array of values for the identifiers from const_names
* @param func1_names NULL terminated array of zero terminated strings of funcs1 identifiers
* @param funcs1 NULL terminated array of function pointers for functions which take 1 argument
* @param func2_names NULL terminated array of zero terminated strings of funcs2 identifiers
* @param funcs2 NULL terminated array of function pointers for functions which take 2 arguments
* @param opaque a pointer which will be passed to all functions from funcs1 and funcs2
* @param log_ctx parent logging context
* @return >= 0 in case of success, a negative value corresponding to an
* AVERROR code otherwise
