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

DMPlexTransform: Allow for plex meshes that do not use standard ordering

DMPlexTransform: Allow for plex meshes that do not use standard ordering

DMPlexTransform assumed that the order of points would be cells->vertices->edges (in 2D).
Some cases, such as a DMForest conv

DMPlexTransform: Allow for plex meshes that do not use standard ordering

DMPlexTransform assumed that the order of points would be cells->vertices->edges (in 2D).
Some cases, such as a DMForest converted to a DMPlex, might have cells->edges->vertices, which results
in points being incorrectly flagged as out-of-range. The new cell type order function has been updated to order cell types by the ordering in the DMPlex.

Added additional tests for DMForest->DMPlex during extrusion.

Closes #1332

See merge request petsc/petsc!6115

Clean up PETSc str ops to use more secure implementations where possible. These include:

- Use PetscStrncpy()/PetscStrlcat()/PetscMemcpy() over PetscStrcpy()/PetscStrcat()
- Use PetscArraycpy() over

Clean up PETSc str ops to use more secure implementations where possible. These include:

- Use PetscStrncpy()/PetscStrlcat()/PetscMemcpy() over PetscStrcpy()/PetscStrcat()
- Use PetscArraycpy() over PetscMemcpy() as appropriate for string buffer copying
- Use built in string from name over hardcoding
- Use sizeof over hardcoded length
- Replace some Strlcat with Strncpy when offset is known
