I think the dof map should be in the FunctionSpace, that way several
functions may share the dof map (which may take time to compute if we
want to do some reordering).

Two functions in the same function space share the mesh, the element
and the dof map (these three define the space) but each function has
its own vector.

I added the FiniteElement class to avoid exposing ufc:: classes
directly. We do the same for ufc::dof_map (but then we have a reason).
It might not be necessary, but it looked more uniform to have

  (Mesh, FiniteElement, DofMap)

instead of

  (Mesh, ufc::finite_element, DofMap)
