DM+Plex: Now classify cells by polytope type
- Defined the polytope type of a cell. added names and special shortcut
pointer like depth - Fixed DMLabelMakeValid() to optimize for contiguous
runs of points - Added cell polytope type label to DM - This needs
special processing, like depth - Added DMPlexGetPointDepth(),
DMPlexGetCellType(), DMPlexGetCellTypeLabel() - DMPlexComputeCellTypes()
infers the cell type for all points using dim/depth/coneSize/ghostCells
- DMPlexGetRawFace(Hybrid)_Internal() now takes the cell type. This
means we can unify the functions later. - Replaced switch(dim/coneSize)
constructs with cell type

Knepley/feature project different spaces

Plex: Now for projection allow 3 DMs: input, output, and auxiliary
- We get the input DM from the input Vec
- Now we can have more general relations between input/output/auxiliary meshes in projectio

Plex: Now for projection allow 3 DMs: input, output, and auxiliary
- We get the input DM from the input Vec
- Now we can have more general relations between input/output/auxiliary meshes in projection and integration
- Added DMEnclosureType
- Added DMGetEnclosureRelation() and DMGetEnclosurePoint()
- Removed DMPlexGetSubpoint() and DMPlexGetAuxiliaryPoint()
- In projection, convert output mesh points to input mesh points
- Coordinates must be reordered after depth label is constructed
- DMPlexLabelAddFaceCells() only adds cells adjacent to faces
- Put in extra debugging for missing point enclosures
- In boundary projection, calculate face data for geometry
- p4est: use known point maps instead of projection to interp from base to coarse

Fix PetscPartitioner and add support for target partition weights

See merge request petsc/petsc!2333

PetscPartitioner: Fix the class in many ways

- DMPlex now weights owned local cells by summing all the local section dofs in the closure of the cell
- Add support for target partition weights via ad

PetscPartitioner: Fix the class in many ways

- DMPlex now weights owned local cells by summing all the local section dofs in the closure of the cell
- Add support for target partition weights via additional PetscSection
- Add centralized option to use vertex weights
- Update man pages
- Rename PetscPartitionerPartition to PetscPartitionerDMPlexPartition since the function is specific to DMPlex
- Add interface to properly partition a graph via PetscPartitionerPartition
- Skip empty processes for distributed graphs in ParMetis and PTSCOTCH
- MatPartitioningPTSCOTCH: match PetscPartitioner calls
- DMPLEX ex24: added target partitioning tests
