BUG: Fixed declarations involving f2py fortranname keyword for
combatibility of Cython BLAS and LAPACK wrappers with OSX.
ENH: Added Cython API for all currently wrapped BLAS routines.
ENH: Added Cython API for all currently wrapped LAPACK routines.
TST: Test to make sure that the Cython BLAS wrappers work.
In particular, test that the functions that use the fortranname keyword in
fblas_l1.pyf.src work properly.
TST: Added a test for one of the Cython LAPACK wrappers.
ENH: Added the function get_linalg_dir to get the directory containing scipy.linalg.
