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

Refactor handling of diagonal marking in *AIJ and SELL matrices

See merge request petsc/petsc!8797

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

- Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

- Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time

- Accessing Mat_SeqXXX->diag now requires the use of MatGetDiagonalMarkers_SeqXXX() except when the current values are known to be correct; for example during numerical factorizations and solves

- Mat_SeqXXX->diag is now never shared among matrices; hence the free_diag flag is gone. That was always a risky proposition since any of the owning matrices could chang the values thus making them incorrect for other owners.

This MR optimize some MAT[SB]AIJ operations related to the diagonal

The longer term goal is to refactor some Mat_SeqXXX non-numeric code to make it easier to also implement it on GPUs. For example,

This MR optimize some MAT[SB]AIJ operations related to the diagonal

The longer term goal is to refactor some Mat_SeqXXX non-numeric code to make it easier to also implement it on GPUs. For example, MatGetDiagonal() and friends

This commit
- MatMarkDiagonal_SeqAIJ/ELL()
- now use change in mat->nonzerostate to determine if it needs to recheck the diagonal locations
- sets diagDense flag for a complete diagonal
- MatInvertDiagonal_SeqAIJ/ELL()
- now uses change in mat->state to determine if diagonal entries and inverses need to be recomputed
- name changed to MatInvertDiagonalForSOR_SeqAIJ/ELL() for code clarity
- Added MatInvertDiagonal_SeqAIJ_Inode() for use by MatSOR_SeqAIJ_Inode()
- now uses change in mat->state to determine if block diagonal entries and inverses need to be recomputed
