+Fix: Corrected pointer iteration range in VectorBase::mean_value()
+and VectorBase::lp_norm() in PETScWrappers namespace to proper handle
+distributed PETSc vectors. Now pointers obtained via VecGetArrayRead()
+iterate only over locally_owned_size(), and results are correctly
+aggregated across processes.
