function from BallTree.h

FIX: do not resize array in knn_brute.

Do not resize the array on k=1.
...
It is more consistent if you always return an array [n_samples,
n_neighbors]. It looks strange, but avoids the need to special-case
other algorithms that depend on this.

Add support for np.float32 matrices in lars_path.
...
Some single-precision routines have had to be ported from cblas. Later
on we could probably remove most of them since new scipy has
triangular_solve function and cholesky_delete could be implemented in
Python.

Refactoring in the svm module.

Created a svm folder and moved relevant sources there. This should not affect
the API, since we are maintaining an __init__ file which handles the imports.
