Vec:

For complex numbers VecNorm(v,NORM_1,) will return the traditional 1 norm of the 2 norm of the complex numbers; that is the 1 norm of the absolutely values of the complex entries. Previously it returned the 1 norm of the 1 norm of the complex entries (what is returned by the BLAS routine asum()). Both are valid norms but most people expect the former.

Added -pc_hypre_boomeramg_nodal_coarsen - where n is from 1 to 6 (see HYPRE_BOOMERAMGSetNodal()) -pc_hypre_boomeramg_vec_interp_variant where v is from 1 to 4 (see HYPRE_BoomerAMGSetInterpVecVariant()) see PCHYPRE to allow taking advantage of MatSetNearNullSpace() for hypre BoomerAMG
