This patch was created using find name *.v  xargs L 1 awk i inplace '{from = 0} /^From/{ from = 1; ever_from = 1} { if (from == 0 && seen == 0 && ever_from == 1) { print "Set Default Proof Using \"Type*\"."; seen = 1 } }1 ' and some minor manual editing

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.

...but it does not work. Hu?

Add both nonexpansive and contractive functors, and bundle them for the general Iris instance as well as the global functor construction This allows us to move the \later in the userdefined functor to any place we want. In particular, we can now have "\later (iProp > iProp)" in the ghost CMRA.

Since functor instances are just used as combinators, there is really no need for functors that are not contractive.

This better seals off their definition. Although it did not give much of a speedup, I think it is conceptually nicer.

This way we avoid many oneoff 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.

This way we can more easily state lemmas for concrete languages for arbitrary global functors.
