Multiopen prover never needed evals to be specified.
The Lagrange interpolation we were doing was pointless. kate_division sheds the constant
term off each time it is invoked because the quotient polynomial isn't affected by it.
This means we were modifying coefficients that end up getting discarded anyway; the
quotient polynomial coefficients are already determined exactly by the leading coefficients
and the fact that a root exists at each of the points.

f49e1e6177 Fix breakage of trait resolution in Rust 1.49.0
Previously, `ChallengeScalar` could use the operator traits defined on
the `F: Field` type it wrapped, due to its `impl Deref<Target = F>`.
This was technically ambiguous, and Rust 1.49.0 makes that ambiguity an
error.

We could fix this by adding operator impls with `ChallengeScalar` on the
RHS, but that would conflict with zcash/halo2#111. Instead we manually
dereference every challenge scalar when used in an arithmetic operation.

7422efca72 s/permutation::Proof::commit/permutation::Argument::commit
Once we refactor the permutation argument implementation to be integrated
as Vec<permutation::Proof>, we can change this again to just map from the
Vec<permutation::Argument> inside ConstraintSystem.
