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

fix(isoperiodic): Orientation correction tolerates no permutations

In certain cases (e.g. Q2 finite elements), a PetscSection may be given
a symmetry because there is no need. This in turn causes `perms` and
`rots` to be returned as NULL. This commit fixes the point orientation
correction functions for isoperiodic to tolerate when `perms` may be
NULL
