fortran: prefer MPI_Comm over integer4 and MPIUNI_FInt over mpiuni_integer4

more f90 fixes: remove PETSC_USING_F90 usage

rename all petsc .F sources to .F90

[this prevents issue like processing include files like mpif.h as f77 fixed source that can cause grief with -i8 build with mpich]

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.

Move to new filter/filter_output method

Change to using filters as arguments to petscdiff. By moving the
manipulation of the input and output into petscdiff, this fixes problems
in using piped commands (based on original, ancient test system), which
is problematic in capturing the right error codes. This also required
fixes for some tests: the "filter: Error: ..." is used to test stderr of
tests.

This fixes problems with REPLACE=1 as reported by @knepley and debugged by @sbalay.
