A method to get the path to the C API headers is missing

There are C header files in astropy/wcs/include, but there is not a method to get the path to these files, the equivalent of

>>> numpy.get_include()
'/usr/lib64/python2.7/site-packages/numpy/core/include'

Without a function like this, it can be quite difficult to find the headers in a platform independent way.
