Remove mesh.compute_boundaries

It's always been a no-op and we're never going to use it.
Add tests of zero form assembly with multiple integrals
mesh: Use entity class information to construct facet sets

We were computing the correct sizes for the PyOP2 sets, but not using
them, so do that.

Note that this necessitates a disgusting hack when computing the
exterior facet boundary node map.  Since the facet sets don't have halo
information, we build a set of the correct size to carry out the
par_loop that populates the map we want rather than iterating over the
facet set.
Add test of upwind flux construction

Construct a BDM1 flux F such that div(F) == D0 where D0 is an upwind DG0
approximation to div(u*D).

io: Ensure output directory exists
Correct convergence orders in nonlinear helmholtz test

To be consistent with solve, use solver_parameters to specify parameters
to the solver.
