Veselin Dobrev 14d552503c Replace calls to ParFiniteElementSpace::Dof_TrueDof_Matrix() with
calls to ParFiniteElementSpace::GetProlongationMatrix() in places
where only the action of the matrix is required.

In ParNonlinearForm::Mult(), use the parallel prolongation operator
instead of relying on the GroupCommunicator.
