      add the infrastructure for Coq to automatically infer the "inG" instances · 95c486ef
      Ralf Jung authored
      I added a new typeclass "inGF" to witness that a particular *functor* is part of \Sigma. inG, in contrast, witnesses a particular *CMRA* to be in there, after applying the functor to "\later iProp".
      inGF can be inferred if that functor is consed to the head of \Sigma, and it is preserved by consing a new functor to \Sigma. This is not the case for inG since the recursive occurence of \Sigma also changes.
      For evry construction (auth, sts, saved_prop), there is an instance infering the respective authG, stsG, savedPropG from an inGF. There is also a global inG_inGF, but Coq is unable to use it.
      
      I tried to instead have *only* inGF, since having both typeclasses seemed weird. However, then the actual type that e.g. "own" is about is the result of applying a functor, and Coq entirely fails to infer anything.
      
      I had to add a few type annotations in heap.v, because Coq tried to use the "authG_inGF" instance before the A got fixed, and ended up looping and expanding endlessly on that proof of timelessness.
      This does not seem entirely unreasonable, I was honestly surprised Coq was able to infer the types previously.

      Use {[_ := _]} for singleton map so we can use ↦ for maps to. · a8591b70
      Robbert Krebbers authored
      The singleton maps notation is now also more consistent with the
      insert <[_ := _]> _ notation for maps.

      Use bundled type classes for ghost ownership. · b07dd0b5
      Robbert Krebbers authored
      * These type classes bundle an identifier into the global CMRA with a proof
        that the identifier points to the correct CMRA. Bundling allows us to get
        rid of many arguments everywhere.
      
      * I have setup the type classes so that we no longer have to keep track of the
        global CMRA identifiers. These are implicit and resolved automatically.
      
      * For heap I am also bundling the name of the heap RA instance. There always
        should be at most one heap instance so this does not introduce ambiguities.
      
      * We now have a "maps to" notation!
