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 stepindex, 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 changes are probably necessary because rewrite now tries harder not to instantiate evars, which it always said it would not do.

It now turns setoid equalities into Leibniz equalities when possible, and substitutes those.

In principle, we could now unseal heap_mapsto, saved_prop_own etc., and mark them as "Typeclass Opaque", and ecancel would still work just as fast as it does now. Thanks to Matthieu for pointing me to this unify feature.

* Use sig instead of sigT: the proof is a Prop after all * Tweak implicit arguments * Shorten proof of sigma

It now traverses terms at most once, whereas the setoid_rewrite approach was travering terms many times. Also, the tactic can now be extended by defining type class instances.
