      It now also contains a non-expansiveness proof.

      Simplify CMRA axioms. · aa947529
      Robbert Krebbers authored
      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.

      COFE distance is no longer trivial at index 0. · 07d525a0
      Robbert Krebbers authored
      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.

      Separate parameters for language and global functor. · 817c0816
      Robbert Krebbers authored
      This way we can more easily state lemmas for concrete languages for
      arbitrary global functors.

      Remove RA from the hierarchy. · b936a5ca
      Robbert Krebbers authored
      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.
