27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func)
* PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg)

PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires
extra work to "parse" C arguments to build a C array of PyObject*.

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.

This change is part of the fastcall project. The change on listsort() is
related to the issue #23507.

45adb3100b Issue #26114: Remove a reference to 'Numerical Recipes'. 
While no copyright violation occurred, the license which
'Numerical Recipes' operates under is not amenable to Python,
so to prevent confusion it's easier to simply remove its mention.

4c8a9a2df3 Issue #8692: Improve performance of math.factorial: 
(1) use a different algorithm that roughly halves the total number of
    multiplications required and results in more balanced multiplications
(2) use a lookup table for small arguments
(3) fast accumulation of products in C integer arithmetic rather than
    PyLong arithmetic when possible.

Typical speedup, from unscientific testing on a 64-bit laptop, is 4.5x
to 6.5x for arguments in the range 100 - 10000.

Patch by Daniel Stutzbach; extensive reviews by Alexander Belopolsky.
