Add TSRHSSplitGet/SetSNES()

Use a different SNES object for TSRHSSplit so that the origina SNES DM still matches the TS DM.

Add a new ARKIMEX solver for fast-slow systems

DM+DS: Create FE with degree bounds
- Add degree bounds to DMCopyFields(), DMCopyDS(), PetscDSCopy(), and PetscDSSelectDiscretizations()
- Add PetscFELimitDegree()

PetscViewer_ExodusII: Allow the viewer to set and query the name and number of variables (results) stored in an exodusII file. Cache this information to avoid repeated calls to exodusII functions.

add extra information for PCView
minimize messages for simple repartitioning
minimize matrix permutations with simple redistribution
expose API to set graph symmetrization (this can be useful in nested solvers when the GAMG block is symmetric but the monolithic matrix is not)
