Add automatic generated fortran support for setting and returning contexts

Major cleanup of the code for setting and returning application (previously called user) contexts
- PetscCtx ctx is now the standard for passing in contexts
- PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFn

Both of these are typedef to void*

Also removed most use of user and userctx for context arguments now consistently named ctx

Improved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran

Improve the propagation of function domain error handling in SNES, especially in the line search routines.

Due to the object layering of SNESLineSearch under SNES there is some code duplication include both SNESLineSearchReason and SNESConvergedReason and SNESCheckFunctionNorm() and SNESLineSearchCheckFunctionNorm() and Jacobian friends

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.

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?
