Changes needed to convert SciPy to work with the new NumPy.

done * scipy_distutils and scipy_base to scipy.disutils and scipy.base
done * Numeric/arrayobject.h to scipy/arrayobject.h
done * Numeric/ufuncobject.h to scipy/ufuncobject.h
done * scipy_test to scipy.test
done * Look for use of descr->zero and descr->ones --- need to be replaced
done * Change use of default_config_dict to Configuration



Changes that should be made someday:

* io rewritten to use internal writing capabilities of arrays
* distributions heavy use of extract and insert (could use fancy indexing?) -- but we should wait until we learn how slow fancy indexing is....)
* Use of old Numeric C-API.  Using it means an extra C-level function call, but ...
* Make use of type addition to extend certain ufuncs with cephes quad types
* Use finfo(foo).bar instead of limits.foo_bar
