This makes stuff more uniform and also removes the need for the [inGFs] type class. Instead, there is now a type class [subG Σ1 Σ2] which expresses that a list of functors [Σ1] is contained in [Σ2].

Use it to prove that tests/barrier_client and tests/heap_lang are adequate.

This commit features:  A simpler model. The recursive domain equation no longer involves a triple containing invariants, physical state and ghost state, but just ghost state. Invariants and physical state are encoded using (higherorder) ghost state.  (Primitive) view shifts are formalized in the logic and all properties about it are proven in the logic instead of the model. Instead, the core logic features only a notion of raw view shifts which internalizing performing frame preserving updates.  A better behaved notion of mask changing view shifts. In particular, we no longer have sideconditions on transitivity of view shifts, and we have a rule for introduction of mask changing view shifts ={E1,E2}=> P with E2 ⊆ E1 which allows to postpone performing a view shift.  The weakest precondition connective is formalized in the logic using Banach's fixpoint. All properties about the connective are proven in the logic instead of directly in the model.  Adequacy is proven in the logic and uses a primitive form of adequacy for uPred that only involves raw views shifts and laters. Some remarks:  I have removed binary view shifts. I did not see a way to describe all rules of the new mask changing view shifts using those.  There is no longer the need for the notion of "frame shifting assertions" and these are thus removed. The rules for Hoare triples are thus also stated in terms of primitive view shifts. TODO:  Maybe rename primitive view shift into something more sensible  Figure out a way to deal with closed proofs (see the commented out stuff in tests/heap_lang and tests/barrier_client).

This avoids recompilation of coq_tactics each time an instance is added.

Similar files (gmap, listset, ...) were already in singular form and matched the name of the set/map data type.

It is just a test case and not really part of the barrier library.

It is not a library; it does not contain code, but instead is a core part of heap_lang.
