[petsc-dev] MPI_UB is deprecated in MPI-2.0

[Isaac, Tobin G]

Pushed a fix that just uses MPI_Type_contiguous(MPI_BYTE, sizeof(),
...), which is not great but I'm only creating the type to work with
PetscSF, so it does the job.  Satish, do you want this as a pull
request, or can you just merge it into next
(`tisaac/feature-remove-mpi-ub`)?

Thanks,
  Toby
