Knepley/feature dm remove hybrid

See merge request petsc/petsc!2614

DM+Plex: Removed the idea of hybrid and ghost cells, in favor of cell type
- Improved Plex tests to work for other cell types
- Plex creation, interpolation, submesh, and refinement routines now set

DM+Plex: Removed the idea of hybrid and ghost cells, in favor of cell type
- Improved Plex tests to work for other cell types
- Plex creation, interpolation, submesh, and refinement routines now set the cell type
- Distribution sorts strata by cell type
- Fixed orientation of prisms from input formats
- Added Plex ex40 to test regular refinement
- CellRefiner is a PetscObject
- dm_plex_cell_refiner chooses the refinement strategy
- Removed SimplexToTensor stuff in favor of ToHex refiner
- Most functions take DMPolytopeType instead of CellRefiner
- CellRefinerInCellTest_Internal()
- CellRefinerGetAffineTransforms_Internal()
- CellRefinerGetAffineFaceTransforms_Internal()
- DMForest now responds to DMPlexGetOverlap() and propagates its overlap to the underlying Plex
- Use DMPlexComputeCellType_Internal() to classify a cell based only on topology
- Added DMPlexGetSimplexOrBoxCells() to replace DMPlexGetInteriorCellStratum()
- Added DM_POLYTOPE_POINT_PRISM_TENSOR
- Added DMPolytopTypeGetDim() and DMPolyTopeTypeGetConeSize()
- Added DMLabelSetStratumBounds()
- Added DMPlexSetCellType()
- Added celltypes to DMView()
- Added DMPolytopeTypeGetNumVertices()

FE+DS: Introduce PetscTabulation to hold tabulated function data

passing around arrays

FE+DS: Introduce PetscTabulation to hold tabulated function data
- This was created to prevent mismatches in sizes I was getting by just
passing around arrays
- FE+FV+DS now hold tabulations
- GetTabulation() --> CreateTabulation() and it creates an object rather
than using DMGetWorkArray(). I put in ComputeTabulation() to reuse
space, but there still may be performance regression.
- Default tabulations are now "cell tabulations"
- The replicas in the tabulation are used to index faces in a face
tabulation

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
