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

Plex+PetscFE: Fixes to allow embedded manifolds
- Add PetscFEGeomMode to describe geometry
- Reorganized PetscFEGeom
- PetscFEGeomCreate(), DMFieldCreateFEGeom() and DMSNESGetFEGeom() now take the PetscFEGeomMode
- J and invJ have dE dimensions
- f1, g1, g2, g3 have dE dimensions
- FIX the dim argument of all point function is really dE because it is used to index the gradients
- Clarified behavior of PetscFEGeomGetCellPoint()
- Now -dm_plex_coordinate_dim can change the coordinate dimension of a mesh created by Plex
- Implicit cell geometry must be used when dim != cdim
