      PetscInitializeNoPointers - Calls PetscInitialize() from C/C++ without the pointers to argc and args

   Collective

   Level: advanced

    Notes: this is called only by the PETSc MATLAB and Julia interface. Even though it might start MPI it sets the flag to
     indicate that it did NOT start MPI so that the PetscFinalize() does not end MPI, thus allowing PetscInitialize() to
     be called multiple times from MATLAB and Julia without the problem of trying to initialize MPI more than once.

     Turns off PETSc signal handling because that can interact with MATLAB's signal handling causing random crashes.
