[issue34049] abs() method accept argument that implement __abs__()

[Windson Yang]

New submission from Windson Yang :

Just like callable() method in 
https://docs.python.org/3/library/functions.html#callable

> ...instances are callable if their class has a __call__() method.

I think we should also mention this in abs(),

abs(x)
Return the absolute value of a number. If x defines __abs__, abs(x) returns 
x.__abs__(). The argument may be an integer or a floating point number. If the 
argument is a complex number, its magnitude is returned.
