The test isn't quite the one in #7421 because that use of algebraic
universes is wrong.

When restricting an evar with candidates, raise an exception if this
restriction would leave the evar without candidates, i.e. unsolvable.
- evarutil: mark restricted evars as "cleared"
They would otherwise escape being catched by the [advance] function
of clenv, and result in dangling evars not being registered to the shelf.
- engine: restrict_evar marks it cleared, update the future goals
We make the new evar a future goal and remove the old one.
If we did nothing, [unshelve tac] would work correctly as it
uses [Proofview.advance] to find the shelved goals, going through
the cleared evar. But [Unshelve] would fail as it expects only
undefined evars on the shelf and throws away the defined ones.

This is a quick fix. Code should be made nicer along these lines:
- try to pass the name of the variable created by "mkletin_goal" in
the monad using "refine_one";
- use a disjunctive type of "inhyps" to indicate when it is
meaningful, rather than using [].

We move the "flag types" to its use place, and mark some arguments
with named parameters better.

When called by auto, `simple apply` still does not respect `Opaque`
because of compatibility issues.

We use an option type instead of returning a pair with a boolean. Indeed, the
boolean being true was always indicating that the returned value was unchanged.
The previous API was somewhat error-prone, and I don't understand why it was
designed this way in the first place.

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.

In locally nameless mode (proof mode) names in the context *must*
be distinct otherwise the term representation makes no sense.

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.

In #6092, `global_reference` was moved to `kernel`. It makes sense to
go further and use the current kernel style for names.
This has a good effect on the dependency graph, as some core modules
don't depend on library anymore.
A question about providing equality for the GloRef module remains, as
there are two different notions of equality for constants. In that
sense, `KerPair` seems suspicious and at some point it should be
looked at.

- Be more precise when trying to clear an hypothesis which
occurs implicitly in a global constant.
- Warns if destruct/induction cannot clear an hypothesis occurring
implicitly in a global.
In the first case, the change in situation
Section A. Variable a:nat. Definition b:=a=a. Goal b=b. clear a.
is:
- before: "a is used in conclusion"
- after: "a is used implicitly in b in conclusion"
In the second case:
Section A. Variable a:nat. Definition b:=a=a. Goal b=b. destruct a.
produces a warning: "Cannot remove a, it is used implicitly in b".

We bootstrap the circular evar_map <-> econstr dependency by moving
the internal EConstr.API module to Evd.MiniEConstr. Then we make the
Evd functions use econstr.

LTAC's `fix` and `cofix` do require access to the proof object inside
the tactic monad when used without a name. This is a bit inconvenient
as we aim to make the handling of the proof object purely functional.
Alternatives have been discussed in #7196, and it seems that
deprecating the nameless forms may have the best cost/benefit ratio,
so opening this PR for discussion.
See also #6171.

We solve some modularity and type duplication problems by moving types
to a better place. In particular:
- We move tactics types from `Misctypes` to `Tactics` as this is their
proper module an single user [with LTAC].
- We deprecate aliases in `Tacexpr` to such tactic types.

We use a lower level function that accesses the proof without raising an
anomaly. This is a direct candidate for backport, so I used a V82 API but
eventually this API should be cleaned up.

- The case 0 makes the code of intros until (and in particular of
Detyping.lookup_quantified_hypothesis_as_displayed more complicated).
- The introduction pattern "*" is compositional while "until 0" is not.

We continue with the work of #402 and #6745 and update most of the
remaining parts of the AST:
- module declarations
- intro patterns
- top-level sentences
Now, parsed documents should be full annotated by `CAst` nodes.

Previously [fun x : Ind@{i} => x : Ind@{j}] with Ind some cumulative
inductive would try to generate a constraint [i = j] and use
cumulativity only if this resulted in an inconsistency. This is
confusingly different from the behaviour with [Type] and means
cumulativity can only be used to lift between universes related by
strict inequalities. (This isn't a kernel restriction so there might
be some workaround to send the kernel the right constraints, but
not in a nice way.)
See modified test for more details of what is now possible.
Technical notes:
When universe constraints were inferred by comparing the shape of
terms without reduction, cumulativity was not used and so too-strict
equality constraints were generated. Then in order to use cumulativity
we had to make this comparison fail to fall back to full conversion.
When unifiying 2 instances of a cumulative inductive type, if there
are any Irrelevant universes we try to unify them if they are
flexible.

This commit was motivated by true spurious conversions arising in my
`to_constr` debug branch.
The changes here need careful review as the tradeoffs are subtle and
still a lot of clean up remains to be done in `vernac/*`.
We have opted for penalize [minimally] the few users coming from true
`Constr`-land, but I am sure we can tweak code in a much better way.
In particular, it is not clear if internalization should take an
`evar_map` even in the cases where it is not triggered, see the
changes under `plugins` for a good example.
Also, the new return type of `Pretyping.understand` should undergo
careful review.
We don't touch `Impargs` as it is not clear how to proceed, however,
the current type of `compute_implicits_gen` looks very suspicious as
it is called often with free evars.
Some TODOs are:
- impargs was calling whd_all, the Econstr equivalent can be either
+ Reductionops.whd_all [which does refolding and no sharing]
+ Reductionops.clos_whd_flags with all as a flag.

We follow the suggestions in #402 and turn uses of `Loc.located` in
`vernac` into `CAst.t`. The impact should be low as this change mostly
affects top-level vernaculars.
With this change, we are even closer to automatically map a text
document to its AST in a programmatic way.

In current code, `Proofview.Goal.t` uses a phantom type to indicate
whether the goal was properly substituted wrt current `evar_map` or
not.
After the introduction of `EConstr`, this distinction should have
become unnecessary, thus we remove the phantom parameter from
`'a Proofview.Goal.t`. This may introduce some minor incompatibilities
at the typing level. Code-wise, things should remain the same.
We thus deprecate `assume`. In a next commit, we will remove
normalization as much as possible from the code.
