We use an algebraic type instead of a pair of a boolean and the corresponding
data. For now, this is isomorphic, but this allows later change in the structure.

We move a bunch of modules (`Impargs`, `Declare`, `Ind_tables`,
`Miscprint`) to their proper place as they were declared in different
`mllib` files than the one in their directory.
In some cases this could be refined but we don't do anything fancy, we
just reflect the status quo.

It used to compute the dependencies of all undefined evars of the
evar_map, while only the dependencies of resolvable evars are necessary.

This is probably the hardest case of them all, because tclABSTRACT fundamentally
relies on the names of universes from the constant instance being the same as
the one in the current goal. Adding to that the fact that the kernel is doing
strange things when provided with a polymorphic definition with body universe
constraints, it turns out to be a hellish nightmare to handle properly.
At some point we need to clarifiy this in the kernel as well, although we
leave it for some other patch.

eval thunks once in prlist_sep_lastsep, make code clearer
add typeclass debug output test
|

As per @JasonGross's request who described a use case for this option in
https://coq.inria.fr/bugs/show_bug.cgi?id=5633 and pending an alternative
solution for this use case.

Instead of returning either an instance or the set of constraints, we rather
return the corresponding abstracted context. We also push back all uses of
abstraction-breaking calls from these functions out of the kernel.
|
|
|
|
Also fixing a bug of get_next_hyp_position when the hypothesis is the
oldest of the context (see test in ltac.v).

It allows in particular to have "Info" on tactic "assert" and
derivatives not to give an "<unknown>".

Except I have disabled the minimization of universes after sections as
it seems to interfere with the STM machinery causing files like
test-suite/vio/print.v to loop when processed asynchronously.
This is very peculiar and needs more investigation as the aforementioned
file does not have any sections or any universe polymorphic definitions!

WIP more of standard library compiles
Also: Matthieu fixed a bug in rewrite system which was faulty when
introducing new morphisms (Add Morphism) command.

WIP: more of the standard library compiles
We have implemented convertibility of constructors up-to mutual
subtyping of their corresponding inductive types. This is similar to
the behavior of template polymorphism.

WIP: trying to get the standard library compile with universe polymorphism
We are trying to prune universes after section ends. Sections add a
load of universes that are not appearing in the body, type or the
constraints.

As we would like to reduce the role of proof_global in future
versions, we start to deprecate old compatibility aliases in `Pfedit`
in favor of the real functions underlying the 8.5 proof engine.
We also deprecate a couple of alias types and explicitly mark the few
remaining uses of `Pfedit`.

Reminder of (some of) the reasons for removal:
- Despite the claim in sigma.mli, it does *not* prevent evar
leaks, something like:
fun env evd ->
let (evd',ev) = new_evar env evd in
(evd,ev)
will typecheck even with Sigma-like type annotations (with a proof of
reflexivity)
- The API stayed embryonic. Even typing functions were not ported to
Sigma.
- Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly
less unsafe ones (e.g. s_enter), but those ones were not marked unsafe
at all (despite still being so).
- There was no good story for higher order functions manipulating evar
maps. Without higher order, one can most of the time get away with
reusing the same name for the updated evar map.
- Most of the code doing complex things with evar maps was using unsafe
casts to sigma. This code should be fixed, but this is an orthogonal
issue.
Of course, this was showing a nice and elegant use of GADTs, but the
cost/benefit ratio in practice did not seem good.

It looks like `Class_tactics` forgot to register a couple of global
variables with the summary, thus creating problems on backtracking.

and
```bash
git grep --name-only ' !"' | xargs sed s'/ !"/!"/g' -i

The rest were manually edited by looking at the results of
```bash
git grep anomaly | grep '\.ml' | grep -v 'anomaly\s*\(~label:"[^"]*"\s*\)\?\(Pp\.\)\?(\(\(Pp.\)\?str\)\?\s*".*\(\.\|!\)")' | grep 'anomaly\($\|[^_]\)' | less
