This mirrors the C++ attribute API better, separates the implementation
of attributes from CustomData slightly, and makes functions simpler,
clearer, and safer.
Also fix an issue with removing an attribute caused by 97712b018d
meant the first attribute with the given type was removed instead of
the attribute with the given name.
