The general idea is to first import/export modules which are further than the current one, and then import/export modules which are close dependencies. This commit tries to use the same order of imports for every file, and describes the convention in ProofGuide.md. There is one exception, where we do not follow said convention: in program_logic/weakestpre.v, using that order would break printing of texan triples (??).

This allows one to make use of recursive ghost state obtained from the recursive domain equation solver.

With Coq master, we otherwise fail to infer instances with subG_savedAnythingΣ, which leads to goals like > looking for (subG > (@savedAnythingΣ (@ofe_funCF val (fun _ : val => laterCF idCF)) > ?cFunctorContractive0) Σ)

I probably tested against a wrong version. This reverts commit 02bc52b4.

This avoids Coq distinguishing iProp and uPred (iResUR _) when it should not.

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].

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).

Requires should always be at the top of a file, Imports can be inside of submodules. It is strange that a Require in a submodule is allowed and then triggers an error when using the whole module. This may be a Coq bug.
