Hash+DMPlex: Changed PetscHashIPut() to eliminate pass-by-ref
- Jed can sleep soundly tonight

DMPlex: If “vtk” label has no cells, do not use it

DMPlex: Use PetscHashIHasKey() to check for membership

DMPlex: Fix DMPlexCheckSkeleton() for submeshes

DMPlex: Added simple DMLabel test

DMPlex: Fix missing restore
Reported-by: Jed Brown <jedbrown@mcs.anl.gov>

DMPlex: Use DMLabelDistribute() in DMPlexDistribute()

DMPlex: Use DMLabelGetStrautmBounds() in DMPlexGetDepth/HeightStratum()

DMPlex: Added DMLabelDistribute()

DMPlex: Added DMLabelGetStratumBounds()

DMPlex: Fixed quadratic behavior of DMLabel insert
- Added hash table for each label value for insertion
- Added arrayValid flag which says whether array data or hash table data is valid
- Convert be

DMPlex: Fixed quadratic behavior of DMLabel insert
- Added hash table for each label value for insertion
- Added arrayValid flag which says whether array data or hash table data is valid
- Convert between representations using DMLabelMakeValid_Private() and DMLabelMakeInvalid_Private()
- Split up allocation of stratumValues and stratumSize/Offsets
- Most functions only use the array representation, but some can use both (should probably expand this with GetStratum)
- Moved the DMLabelFIlter() function
