There are now two proof mode tactics for dealing with modalities:  `iModIntro` : introduction of a modality  `iMod pm_trm as (x1 ... xn) "ipat"` : eliminate a modality The behavior of these tactics can be controlled by instances of the `IntroModal` and `ElimModal` type class. We have declared instances for later, except 0, basic updates and fancy updates. The tactic `iMod` is flexible enough that it can also eliminate an updates around a weakest pre, and so forth. The corresponding introduction patterns of these tactics are `!>` and `>`. These tactics replace the tactics `iUpdIntro`, `iUpd` and `iTimeless`. Source of backwards incompatability: the introduction pattern `!>` is used for introduction of arbitrary modalities. It used to introduce laters by stripping of a later of each hypotheses.

And also rename the corresponding proof mode tactics.

Before, it failed when these tactics were invoked with persistent hypotheses. The new behavior is more convenient when using these tactics to build other tactics.

Before this commit, given "HP" : P and "H" : P ★ Q with Q persistent, one could write: iSpecialize ("H" with "#HP") to eliminate the wand in "H" while keeping the resource "HP". The lemma: own_valid : own γ x ⊢ ✓ x was the prototypical example where this pattern (using the #) was used. However, the pattern was too limited. For example, given "H" : P₁ ★ P₂ ★ Q", one could not write iSpecialize ("H" with "#HP₁") because P₂ ★ Q is not persistent, even when Q is. So, instead, this commit introduces the following tactic: iSpecialize pm_trm as # which allows one to eliminate implications and wands while being able to use all hypotheses to prove the premises, as well as being able to use all hypotheses to prove the resulting goal. In the case of iDestruct, we now check whether all branches of the introduction pattern start with an `#` (moving the hypothesis to the persistent context) or `%` (moving the hypothesis to the pure Coq context). If this is the case, we allow one to use all hypotheses for proving the premises, as well as for proving the resulting goal.

Also make those for introduction and elimination more symmetric: !% pure introduction % pure elimination !# always introduction # always elimination !> later introduction > pat timeless later elimination !==> view shift introduction ==> pat view shift elimination

This makes clear that we do not range over Coq terms.
