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. This closes issue #5576 .

Issues #3167 , #3682 : tests for math.log and math.log10 were failing on

Solaris and OpenBSD. Fix this by handling special values and domain
errors directly in mathmodule.c, passing only positive nonspecial floats
to the system log/log10.
