SNES+Plex: use all cell values to interpolate to face

Previously the boundary residual/jacobian routines interpolated to face
quadrature points by taking the closure of those faces and using a
separate boundary discretization. This only worked if there were dofs on
faces and the discretization order of the cell and boundary were the
same.
Inverse element jacobians are now calculated from adjacent cells
to also have information on normal derivatives.

Boundary conditions are better conceptually matched to the PetscDS,

We now have an example (ts/examples/tutorials/ex11.c) where we can
use either DMPlex or DMP4est to handle adaptivity when time stepping.
We have tried to minimize the amount of code that is specialized to the
different DMs, and in the future more work can be done to improve this
interface.
