  Refactor some longobject internals:  PyLong_AsDouble and _PyLong_AsScaledDouble
  (the latter renamed to _PyLong_Frexp) now use the same core code.  The
  exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the
  previously used int, and no longer needs scaling by PyLong_SHIFT.  This
  frees the math module from having to know anything about the PyLong
  implementation.
