Uses MPI_COMM_WORLD to display rank, because this may be called in PetscFinalize() after PETSC_COMM_WORLD has been freed.
When called in PetscFinalize() dumps only the allocations that have not been properly freed
PetscMallocView() prints a list of all memory ever allocated

The calling sequence is PetscMallocDump(PetscErrorCode ierr). A fp parameter is not supported.
