The finiteness was needed to have the axiom of choice over the domain. This axiom is not needed if cmra_extend is in Type.

Rename `UCMRA` → `Ucmra` Rename `CMRA` → `Cmra` Rename `OFE` → `Ofe` (`Ofe` was already used partially, but many occurences were missing) Rename `STS` → `Sts` Rename `DRA` → `Dra`

For obsolete reasons, that no longer seem to apply, we used ∅ as the unit.

Instead, I have introduced a type class `Monoid` that is used by the big operators: Class Monoid {M : ofeT} (o : M → M → M) := { monoid_unit : M; monoid_ne : NonExpansive2 o; monoid_assoc : Assoc (≡) o; monoid_comm : Comm (≡) o; monoid_left_id : LeftId (≡) monoid_unit o; monoid_right_id : RightId (≡) monoid_unit o; }. Note that the operation is an argument because we want to have multiple monoids over the same type (for example, on `uPred`s we have monoids for `∗`, `∧`, and `∨`). However, we do bundle the unit because:  If we would not, the unit would appear explicitly in an implicit argument of the big operators, which confuses rewrite. By bundling the unit in the `Monoid` class it is hidden, and hence rewrite won't even see it.  The unit is unique. We could in principle have big ops over setoids instead of OFEs. However, since we do not have a canonical structure for bundled setoids, I did not go that way.

Cancelable elements are a new way of proving local updates, by removing some cancellable element of the global state, provided that we own it and we are willing to lose this ownership. Identityfree elements are an auxiliary that is necessary to prove that [Some x] is cancelable. For technical reasons, these two notions are not defined exactly like what one might expect, but also take into account validity. Otherwise, an exclusive element would not be cancelable or idfree, which is rather confusing.
