CHKERRV: fix assignment to ierr

When using at CHKERRV(PetscCall(...)), we can't assign to the argument.

CHKERRQ: allow passing the entire function call

Code formatters like clang-format and astyle behave poorly with line
wrapping and the PETSc convention of hanging CHKERRQ(ierr) at the ends
of lines.

CHKERRQ: allow passing the entire function call

Code formatters like clang-format and astyle behave poorly with line
wrapping and the PETSc convention of hanging CHKERRQ(ierr) at the ends
of lines. They do a better job if one writes

CHKERRQ(PetscFunction(with,args));

even if when wrapping long lines. This commit enables the above style
by expanding ierr only once inside the CHKERRQ(ierr) macro.

Add support for users to pass in FFLAGS the option for promoting integers to 8 bytes.

Tested for ifort and gfortran

Tested with MPICH and OpenMPI and MPI-Uni

Since MPI does not provide any mechanism for integer promotion the code very crudely adjusts the
values in the mpif.h to mark them as 4 byte integers this is not neccessary portable for all MPI implementations

This is an extremely fragile option that we should probably not be supporting.

Users must insure their Fortran codes passes only 4 byte integers to MPI calls

PETSc Fortran examples were all fixed to explicitly use 4 byte integers for MPI calls.
