cleanup suggestions by @BarrySmith

also noticed a few stray functions not marked as external and put them
into modules

this allows for argument checking

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

add typedef for functions passed to SNESSetFunction() etc to match approach in TS

I never liked Jed's use of typedef for function prototypes for a couple of reasons

1) you don't see immediately that the argument to the function is a function pointer instead of standard variable when looking at source
2) you don't see at the exact location in the code the prototype of the function being passed in

but there is something to say for using these typedefs so

I've prototyped the change for SNES but slightly differently than what Jed did for TS

1) I append the typedef with _Ftn to mark that it is a function (helping to relieve the problem 1 above)
2) I made the typedef to be for a function, not a function pointer so it can also be used directly for things like

PETSC_EXTERN SNESJacobian_Ftn SNESComputeJacobianDefault;

I think the TS usage could be switched to this style without user code breakage, and deprecate the current TS typedef

Thoughts?

Just do SNES the same way as TS and live with less clarity?

Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if def

Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if defined(PETSC_USE_LOG)
PetscLogEvent event;
#endif
```

- Having global counters like petsc_TotalFlops externed event
if !PetscDefined(USE_LOG) helps to remove a lot of needless
`#ifdef`s around code that can instead be placed in
`if (PetscDefined(USE_LOG)) {}` blocks.
