PetscSF: Register logging events
PetscSF: Added logging
DMPlex: Bug fix for interpolated adjacency formation
DMPlex: Fast adjacency graph construction for interpolated meshes
DMPlex: Fixed error in new events
DMPlex: More events for distribution
DMPlex: Fixed allocation bug in reordering
DMPlex: Fixed mismatched Malloc2 in reordering
DMLabel: Split Malloc3 into Malloc2 and Malloc
Hash+DMPlex: Changed PetscHashIPut() to eliminate pass-by-ref - Jed can sleep soundly tonight
DMPlex: Use PetscHashIHasKey() to check for membership
Hash; Added PetscHashIHasKey() - PetscHashIMap does not match the documentation
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 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
Hash: Added PetscHashIPut() and PetscHashIDel() - Removed unused variable
