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.

The ExtrOCamlInt63 module can be required to map primitives from the Int63
module to their OCaml implementation (module Uint63 from the kernel).

- Improved reification for Micromega (support for #8764)
- Fixes #9268: Do not take universes into account in lia reification
Improve #9291 by threading the evar_map during reification.
Universes are unified.
- Remove (potentially cyclic) dependency over lra for Rle_abs
- Towards a complete simplex-based lia
fixes #9615
Lia is now exclusively using cutting plane proofs.
For this to always work, all the variables need to be positive.
Therefore, lia is pre-processing the goal for each variable x
it introduces the constraints x = y - z , y>=0 , z >= 0
for some fresh variable y and z.
For scalability, nia is currently NOT performing this pre-processing.
- Lia is using the FSet library
manual merge of commit #230899e87c51c12b2f21b6fedc414d099a1425e4
to work around a "leaked" hint breaking compatibility of eauto

- Made generation of index page fail if a file is missing in list or
listed but unbound in existing theories
- Added a file hidden-files to optionally list library files not to show
in the index page (though it is currently empty)
- Added directory Unicode (why not to have it after all?)
