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

cc1: all warnings being treated as errors

Fixed by removing the f2c generated shift in nn[] that made the compiler think nn[] might be accessed out of range

Convert MPI error type to PETSc error with string message for all MPI calls

Now PETSc examples will ONLY return PETSc error codes and never MPI error codes directly so we can understand and post-process their
errors better.

The test harness will now automatically retry tests that fail with MPI, this may help with Intel MPI that produces
seemingly random failures.
