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

Complete usage of PetscVoidFn and PetscErrorCodeFn and introduce PetscFortranCallbackFn

Introduce PetscFortranCallbackFn to be used instead of PetscVoidFn for Fortran callback functions

Also fix incorrect use of SNESFunctionFn and SNESJacobianFn in SNES Fortran manual stub

Change use of void (*)(void) and void (**)(void) in the PETSc API to PetscVoidFn * and PetscVoidFn ** or PetscErrorCodeFn * or PetscErrorCodeFn **

distinguish Boolean and Integer

MPI_Comm_get_attr has PetscMPIInt as flag argument, not PetscBool. Name
this flag "iflg" (was used somewhere already).
Use MPI_LAND instead of MPI_BAND for logical operations instead of
MPI_MIN, MPI_MAX, and MPI_LAND.

Note: Most of the previous code was probably working as intended, I did
the changes when debugging error related to the use of standard C Bool and
kept them because it took me a while to understand that MPI has integer
flags and PETSc has Booleans. Using different names makes this clear,
but was and is not done consistently.

Add #define PetscObjectNullify(o) o%v = PETSC_FORTRAN_TYPE_INITIALIZE to allow Fortran users to reset a variable to behave as if it had just been declared and not yet been assigned a PETSc object.

R

Add #define PetscObjectNullify(o) o%v = PETSC_FORTRAN_TYPE_INITIALIZE to allow Fortran users to reset a variable to behave as if it had just been declared and not yet been assigned a PETSc object.

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

Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
