They're new as public, documented functions.

Writing code targeting also earlier Scipy versions is possible in
principle.

This is backward and forward compatible:

    dgemm, = get_blas_funcs(['gemm',], [np.array([1.0])])

Note that `.cblas` is not available at all on all platforms, and the
functions it contains vary with Scipy versions. Also, both `.cblas`
and `.fblas` submodules are deprecated.
