The only drawback is that we have to restrict iprod to finite types, but that is fine.

So, only use the type class for contractive functors.

Add both non-expansive and contractive functors, and bundle them for the general Iris instance as well as the global functor construction This allows us to move the \later in the user-defined functor to any place we want. In particular, we can now have "\later (iProp -> iProp)" in the ghost CMRA.

Since functor instances are just used as combinators, there is really no need for functors that are not contractive.

This cleans up some ad-hoc stuff and prepares for a generalization of saved propositions.

It now also contains a non-expansiveness proof.

I have simplified the following CMRA axioms: cmra_unit_preservingN n x y : x ≼{n} y → unit x ≼{n} unit y; cmra_op_minus n x y : x ≼{n} y → x ⋅ y ⩪ x ≡{n}≡ y; By dropping off the step-index, so into: cmra_unit_preservingN x y : x ≼ y → unit x ≼ unit y; cmra_op_minus x y : x ≼ y → x ⋅ y ⩪ x ≡ y; The old axioms can be derived.

The performance gain seems neglectable, unfortunatelly...

This way it behaves better for discrete CMRAs.

This better seals off their definition. Although it did not give much of a speedup, I think it is conceptually nicer.

This way we avoid many one-off indexes and no longer need special cases for index 0 in many definitions. For example, the definition of the distance relation on option and excl has become much easier. Also, uPreds no longer need to hold at index 0. In order to make this change possible, we had to change the notions of "contractive functions" and "chains" slightly. Thanks to Aleš Bizjak and Amin Timany for suggesting this change and to help with the proofs.

Instead, we have just a construction to create a CMRA from a RA. This construction is also slightly generalized, it now works for RAs over any timeless COFE instead of just the discrete COFE. Also: * Put tactics and big_ops for CMRAs in a separate file. * Valid is now a derived notion (as the limit of validN), so it does not have to be defined by hand for each CMRA. Todo: Make the constructions DRA -> CMRA and RA -> CMRA more uniform.
