DM+FE: Allow multiple cohesive fields

See merge request petsc/petsc!4616

FE+DS: Now hybrid integration uses side 2 for fault operations
- Added cohesive offsets of PetscDS
- Fixed offsets and handling of dimension

DM+FE: Allow multiple cohesive fields
- Changed name from "hybrid" cell to "cohesive" cell
- Fixed check for cohesive field in PetscFE and DM
- Fixed DMCreateDS() for new scheme
- Added PetscDSIsCohe

DM+FE: Allow multiple cohesive fields
- Changed name from "hybrid" cell to "cohesive" cell
- Fixed check for cohesive field in PetscFE and DM
- Fixed DMCreateDS() for new scheme
- Added PetscDSIsCohesive() and PetscDSGetNumCohesive()
- Replaced PetscDSGetHybrid() with PetscDSGetCohesive() and
PetscDSSetHybrid() with PetscDSSetCohesive()
- Added PetscDSGetFieldOffsetCohesive()
- Fixed hybrid Jacobian integration
- Hybrid Jacobian integration needs to know the side of the interface, just like residual integration
- Needs to use cohesive field offsets
- Update takes the side as an argument

Jacobian
- Affine worked because the last Jacobian was always being used

DM+Plex: Boundary integration functions are now stored in a PetscWeakForm held in the Boundary object
- Boundary residual/Jacobian functions now take a form key
- Now store DMLabel in DSBoundary
- Improved Boundary, Weak Form, and DS viewers
- Remove DMCopyBoundary(), DMCopyDisc() is sufficient
- Need DMTransferDS_Internal() to create new DS with label in the correct DM
- Correct all DMAddBoundary() in tests
- Allow DMBoundary to hold just a label name if necessary since p4est is missing labels in a lot of places
- Fix propagating coordinate dimension in DS
