Change the scheme for reductions. Before, reductions was done over the full

grid functions using CCTK_Reduce. Now, reductions are done alongside the
computations into local arrays and then these are reduced using
CCTK_ReduceLocArrayToArray1D. This is much more efficient. In addition
OpenMP directives are added to allow for mixed MPI/OpenMP usage.
