Remove use of PetscDataType from VTK code and other trivial location.

Reason: PetscDataType is duplicative to MPI_Datatype therefor we hope to limit its
use and perhaps eventually completely remove

PetscViewerDestroy_ASCII: clean up stdout and stderr attributes from MPI_Comm

PetscViewerDestroy_ASCII: clean up stdout and stderr attributes from MPI_Comm

Since -log_view is processed after PetscObjectRegisterDestroyAll() in
PetscFinalize(), it can attempt to access attributes from
PetscViewerASCIIGetStdout(). When there are no references to the inner
communicator, it will be freed no later than
PetscObjectRegisterDestroyAll() and thus all attributes become unset.
But if there is any reference to the inner communicator, as in the
example below with the dummy PetscContainer (the type does not matter),
it remains after PetscObjectRegisterDestroyAll() and thus any stale
attributes remain accessible.

#include <petscviewer.h>

int main(int argc,char **args)
{
PetscErrorCode ierr;
PetscViewer view;
PetscContainer container;

ierr = PetscInitialize(&argc,&args,(char*)0,NULL);CHKERRQ(ierr);
ierr = PetscContainerCreate(PETSC_COMM_WORLD,&container);CHKERRQ(ierr);
ierr = PetscViewerASCIIGetStdout(PETSC_COMM_WORLD,&view);CHKERRQ(ierr);
ierr = PetscFinalize();
return ierr;
}

Now one can use --with-fc=gfortran --with-fortran-bindings=0 to detect fortran compiler properly
[for externalpacakge use - for eg: scalapack] but avoid building PETSc fortran bindings in library and modules.

Also disable sowing when with-fortran-bindings is disabled

Fix makefiles (corresponding to fortran bindings) to consistantly use PETSC_HAVE_FORTRAN

Also remove unused PETSC_USE_FORTRAN_DATATYPES flag
