New submission from Christian Heimes:

The patch adds several small enhancements to the math module and pyport.h.

* Py_MATH_PI and Py_MATH_E in long double precision
* Py_IS_NAN and Py_IS_INFINITY use isnan() and isinf() functions were
available (checked by configure)
* isnan and isinf for the math module
* Bessel (1st and 2nd kind), erf, erfc, lgamma function for math module.
They are defined in almost (or all?) math libraries.

Together with http://bugs.python.org/issue1635 it implements most of PEP
754.
