* knepley/fix-pylith-parallel: (22 commits)
DMPlex: In refinement, merge hybrid and non-hybrid SF creation (should be done for everything) - If missing, define *Max as *End - Fixed bound on hybrid 2D simplicial hybrid cell refinement - Fixes bug in which wrong remote point number was calculated if local process had no hybrid cells, but remote process did so refiners were mismatched
DMPlex: Fix for hybrid refinement - Must correct offsets when neighbor process has no hybrid points
DMPlex: Fix hex hybrid refinement SF - Fixed offset - Fixed number of cell faces - Fixed missing edge offset - Fixed number of cells faces - FIxed missing edge offset
PetscSection: Must initialize remoteOffsets
DMPlex: Fixed cohesive cell creation for clamped boundaries - Explicitly tag cross-edges (edges with two clamped endpoints) with 2 in boundary label - Add cross-edge to vertices when looking for things that need split points replaced - Remove extra check for boundary vertices
DMPlex: Fixes for marking cohesive submesh - Do not mark points as split which are in the boundary label - Mark boundary points from label as unsplit
DMPlex: Changing meaning of boundary label in DMPlexLabelCohesiveComplete() - Now it marks vertices already present in the original label - We mark these as unsplit, and ignore their stars - Remove old code
