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 PetscOptionsGetViewer() so it works in a thread-safe way

When PetscOptionsGetViewer() returns, for example, PETSC_VIEWER_STDOUT_SELF the same object is shared
by all threads that call PetscOptionsGetViewer(). In the previous code PetscObjectReference() and
dereference (via PetscViewerDestroy() where called on the viewer by multiple threads after the viewer
was accessed thus corrupting the object.

This branch introduces a PetscOptionsRestoreViewer() that allows not doing the referencing and dereferencing
on persistant viewers, thus removing the specific race condition above.

Other possible solutions include

Use a lock on each PetscObjectReference/Dereference() just in case they are shared. Could be time consuming so one
could mark each object as either threadshared or independent and only do the locks on threadshared objects. This lowers
the cost but would require more extensive changes to PETSc infrastructure. And I do not know if this shared/not shared model
is what we need in the long run, though it might be.
