Log Message:
-----------
ENH: core: Allow user to pass in output array for dot()

This avoids the memory allocation. It is strict in checking that the
types are correct, but since it is intended as an optimisation, it
should only be used when the user knows what they are doing.

The out parameter is added both to the BLAS and non-BLAS versions of dot().
Tests are included.
