place all the include statements at the top

Repeated inclusion in multiple location, e.g. at the start of a
module or function is not needed. This becomes clear if all includes are
outside of the actual Fortran code.
Added regex to check that with the help of @sbalay

Fortran 90: fully embrace After 34 years!

- deprecate use of 'F90' in Fortran function names
- use Fortran pointers when appropriate
- the new Fortran API is not backward compatible with previous versions!
- also clean up inconsistent PETSc code detected by new Fortran generation tools
- drop use of bfort
- automatically generate all the Fortran PETSc objects, enums etc from the include files
- generate most of the Fortran interface definitions and functions from the source code
- simplify the number and organization of Fortran modules

This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGER
Pass arrays (and not scalar values) when the argument is expecting an array; this means replace, for example, the argument v with [v]
Use PetscObjectIsNull(obj) to check if the object is NULL, instead of obj == PETSC_NULL_XXX

The compiler will now automatically prevent you from using the wrong argument type for the first three bullets above
This will also require an update sowing with the new sowing branch this MR is using.
