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

ts: TSEvaluationTimes works over multiple calls to TSSolve()

A few changes to make this work:
- Have multiple calls to `TSSetEvaluationTimes()` reset all index
counters in addition to `sol_times` and `sol_vecs`
- Move the allocation of `sol_vecs` into TSSolve itself
- At the top of `TSSolve()`, check if the initial condition has already
been written to `sol_times`

Also includes some minor renaming and comment changes
