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

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

SNESLineSearch: fix computation of directional derivative in the case of the VI solvers

The two line search algorithms bisection and critical point work with the directional derivative, assuming that F(x) = grad G(x).
However, when working with the variational inequality solvers, the constraints were not correctly considered when computing the directional derivative.
This commit introduces a new linesearch->ops->vidirderiv function which correctly considers the constraints (similar to linesearch->ops->viproject and linesearch->ops->vinorm).

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?
