The plan was to move blas/lapack wrappers from scipy.linalg
to scipy.lib.blas/lapack so that other scipy subpackage could use them
without importing the whole scipy.linalg. It's still work in progress plan..
Blas/lapack wrappers in scipy.lib are improved versions found in
scipy.linalg,
just replacing the usage of scipy.linalg.blas/lapack with using
scipy.lib.blas/lapack is unfinished.
