We move `binder_kind` to the pretyping AST, removing the last data
type in the now orphaned file `Decl_kinds`.
This seems a better fit, as this data is not relevant to the lower
layers but only used in `Impargs`.
We also move state keeping to `Impargs`, so now implicit declaration
must include the type. We also remove a duplicated function.

We update the URLs to the new ones, even if the previous continue to work.

This file is unrelated to library, but to pretyping/unification.
This commit, along with others already submitted go towards the goal
of `library` containing only the handling of library objects.

This source of slowness has been observed in VST, but it is probably
pervasive. Most of the unification problems are not mentioning evars,
it is thus useless to compute the set of frozen evars upfront.
We also seize the opportunity to reverse the flag, because it is always
used negatively.

Fixes #10452
|
|
We place control attributes on their own, datatype, similarly to
regular attributes.
This is a step towards fixing #10452 , as we can now decouple control
attributes from the vernac AST itself, allowing to pass them
independently.

`Mlutil.simpl` and `Mlutil.atomic_eta_red` did some unsound eta-reductions as
follows:
(fun x0 ... xn => MLexn x0 ... xn) ->eta MLexn.
`MLexn` raises an exception thus is not a value in OCaml. So the above
simplification may change the behavior of extracted programs. This patch
restricts `atomic_eta_red` to eta-redexes whose core is both atomic and value.

This lets us remove the passing around of "status" in comassumption
and generally makes highlighting axiom adding lines in coqide more
reliable as there's no need for per-command code.
If a command adds multiple axioms it will emit AddedAxiom multiple
times, this doesn't seem to be a problem though.
We may wonder if "Fail Fail Axiom" should be highlighted as
"Axiom" (both before and after this commit it is).

* Borrow ideas from the Setoid refman documentation:
https://coq.inria.fr/refman/addendum/generalized-rewriting.html#first-class-setoids-and-morphisms
* Introduce a relation with the following signature:
[Rel : forall (m n : nat) (s : Setoid m n), car s -> car s -> Prop]
|
|
Changes:
* Add ssrclasses.v that redefines [Reflexive] and [iff_Reflexive];
* Add ssrsetoid.v that links
[ssrclasses.Reflexive] and [RelationClasses.Reflexive];
* Add [Require Coq.ssr.ssrsetoid] in Setoid.v;
* Update ssrfwd.ml accordingly, using a helper file ssrclasses.ml that
ports some non-exported material from rewrite.ml;
* Some upside in passing: ssrfwd.ml no more depends on Ltac_plugin;
* Update doc and tests as well.
Summary:
* We can now use the under tactic in two flavors:
- with the [eq] or [iff] relations: [Require Import ssreflect.]
- or a [RewriteRelation]: [Require Import ssreflect. Require Setoid.]
(while [ssreflect] does not require [RelationClasses] nor [Setoid],
and conversely [Setoid] does not require [ssreflect]).
* The file ssrsetoid.v could be skipped when porting under to stdlib2.
