reference was defined as Ident or Qualid, but the qualid type already
permits empty paths. So we had effectively two representations for
unqualified names, that were not seen as equal by eq_reference.
We remove the reference type and replace its uses by qualid.

I let open several questions about fixes to the kernel which maybe
were not critical.
I skipped what seemed to have been bugs in beta-releases.
Need double-checks, decision about the format, etc.

We had mostly used absolute links in the past.
I just discovered that GitHub recommends using relative links instead:
https://help.github.com/articles/basic-writing-and-formatting-syntax/#relative-links
and indeed my Emacs Markdown mode can handle relative links but doesn't
interpret absolute links relatively to the root of the git repository.

Bumping to 4.02.3 was decided some time ago in the WG, however a
couple of places escaped updating.

It was actually a hack since those names are never used to represent
values, only to be passed as arguments to bytecode instructions. So
instead of reusing the structured_constant type, we follow the same
pattern as switch annotations.

Packages such as `menhir` or `elpi` are fragile w.r.t. updates, so
allowing a non-deterministic install in the Dockefile seems risky. We
have found trouble with Menhir in the past. We thus specify a concrete
version for all `CI_OPAM` packages.

We also add remove `hevea` from `apt` dependencies as it hasn't been
needed since #7466 and add `texlive-science` which is needed to build
the `source-doc` target due to the `textgreek` package being used.

This is needed for CI packages that use `META.coq` such as in
https://github.com/coq/coq/pull/7656 .

We bump Windows builds to 4.06.1, IMHO it makes sense to use the
latest OCaml version to build on that platform due to the support
status and number of fixes.

Continuing the interface cleanup we place `Constrexpr` in the
internalization module, which is the one that eliminates it.
This slims down `pretyping` considerably, including removing the
`Univdecls` module which existed only due to bad dependency ordering
in the first place. Thanks to @ Skyskimmer we also remove a duplicate
`univ_decl` definition among `Misctypes` and `UState`.
This is mostly a proof of concept yet as it depends on quite a few
patches of the tree. For sure some tweaks will be necessary, but it
should be good for review now.
IMO the tree is now in a state where we can could easy eliminate more
than 10 modules without any impact, IMHO this is a net saving API-wise
and would help people to understand the structure of the code better.

We remove most of what was deprecated in `Term`. Now, `intf` and
`kernel` are almost deprecation-free, tho I am not very convinced
about the whole `Term -> Constr` renaming but I'm afraid there is no
way back.
Inconsistencies with the constructor policy (see #6440) remain along
the code-base and I'm afraid I don't see a plan to reconcile them.
The `Sorts` deprecation is hard to finalize, opening `Sorts` is not a
good idea as someone added a `List` module inside it.

We now have only two notions of environments in the kernel: env and
safe_env.

We make the vernacular implementation self-contained in the `vernac/`
directory. To this extent we relocate the parser, printer, and AST to
the `vernac/` directory, and move a couple of hint-related types to
`Hints`, where they do indeed belong.
IMO this makes the code easier to understand, and provides a better
modularity of the codebase as now all things under `tactics` have 0
knowledge about vernaculars.
The vernacular extension machinery has also been moved to `vernac/`,
this will help when #6171 [proof state cleanup] is completed along
with a stronger typing for vernacular interpretation that can
distinguish different types of effects vernacular commands can perform.
This PR introduces some very minor source-level incompatibilities due
to a different module layering [thus deprecating is not
possible]. Impact should be relatively minor.

We address the easy ones, but they should probably be all removed.

We remove the `fix N / cofix N` forms from the tactic language. This
way, these tactics don't depend anymore on the proof context, in
particular on the proof name, which seems like a fragile practice.
Apart from the concerns wrt maintenability of proof scripts, this also
helps making the "proof state" functional; as we don't have to
propagate the proof name to the tactic layer.
