Changes:  We no longer have a different syntax for specializing a term H : P ★ Q whose range P or domain Q is persistent. There is just one syntax, and the system automatically determines whether either P or Q is persistent.  While specializing a term, always modalities are automatically stripped. This gets rid of the specialization pattern !.  Make the syntax of specialization patterns more consistent. The syntax for generating a goal is [goal_spec] where goal_spec is one of the following: H1 .. Hn : generate a goal using hypotheses H1 .. Hn H1 .. Hn : generate a goal using all hypotheses but H1 .. Hn # : generate a goal for the premise in which all hypotheses can be used. This is only allowed when specializing H : P ★ Q where either P or Q is persistent. % : generate a goal for a pure premise.

iSpecialize and iDestruct. These tactics now all take an iTrm, which is a tuple consisting of a.) a lemma or name of a hypotheses b.) arguments to instantiate c.) a specialization pattern.

These tactics are superfluous:  iPure H as pat => iDestruct H as pat  iPersistent H => iSpecialize H "!"

 It can now also frame under later.  Better treatment of evars, it now won't end up in loops whenever the goal involves subformulas ?P and it trying to apply all framing rules eagerly.  It no longer delta expands while framing.  Better clean up of True subformulas after a successful frame. For example, framing "P" in "▷ ▷ P ★ Q" yields just "Q" instead of "▷ True ★ Q" or so.

This gets rid of the (ambiguous) notation %l, because we can declare LitLoc as a coercion. It also shortens the code.

This reverts commit 3cc38ff6. The reverted pure hypotheses and variables appear in the wrong order.

Since strip_later is doing a good job stripping laters in the conclusion, these tactics are thus no longer needed. Also, wp_finish now properly converts the result in a primitive viewshift in case it is not a weakestpre.

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.

make the global functor stuff in the various constructions more uniform; change it such that barrier/proof does not have to repeat the functors it needs

Ralf Jung authored
add a version of [cancel] that works with goals of the form [_  pvs _]; and use that for the barrier proof

This cleans up some adhoc stuff and prepares for a generalization of saved propositions.
