- Provide new helper functions in `Goptions` on the model of
`declare_bool_option_and_ref`;
- Use these helper functions in many parts of the code base
(encapsulates the corresponding references);
- Move almost all options from `declare_string_option` to
`declare_stringopt_option` (only "Warnings" continue to use the
former). This means that these options now support `Unset` to get
back to the default setting. Note that there is a naming
misalignment since `declare_int_option` is similar to
`declare_stringopt_option` and supports `Unset`. When "Warning" is
eventually migrated to support `Unset` as well, we can remove
`declare_string_option` and rename `declare_stringopt_option` to
`declare_string_option`.
- For some vernac options and flags that have an equivalent
command-line option or flag, implement it like the standard `-set`
and `-unset`.

Add headers to a few files which were missing them.
|

We also remove trailing whitespace.
Script used:
```bash
for i in `find . -name '*.ml' -or -name '*.mli' -or -name '*.mlg'`; do expand -i "$i" | sponge "$i"; sed -e's/[[:space:]]*$//' -i.bak "$i"; done
```

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.

This lets us avoid having to cache the SearchBlacklist.elements call
in search as we can just use the set module's for_all function.

I don't think there's a reason to treat such variables more severely
than unbound variables. This anomaly is often raised by debug printers
(e.g. when studying complex scenarios using `Set Unification Debug`),
and so makes debugging less convenient.
Fixes #3754, fixes #10026.

One other call still remains, but will require to refactor some
section-handling code.

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.

We move syntax for universes from `Misctypes` to `Glob_term`. There is
basically no reason that this type is there instead of the proper
file, as witnessed by the diff.
Unfortunately the change is not compatible due to moving a type to a
higher level in the hierarchy, but we expect few problems.
This change plus the related PR (#6515) moving universe declaration to
their proper place make `Misctypes` into basically an empty file save
for introduction patterns.

Moreover, when there are at least two clauses and the last most
factorizable one is a disjunction with no variables, turn it into a
catch-all clause.

to deactivate the first behavior (deactivating the first one
deactivates also the second one).
E.g. printing
match x with Eq => 1 | _ => 0 end
gives
match x with

end
or (with default clause deactivates):
match x with

We do up to `Term` which is the main bulk of the changes.

To this extent we factor out the relevant bits to a new file,
ltac_pretype.

The old algorithm was relying on list membership, which is O(n). This was
nefarious for terms with many binders. We use instead sets in O(log n).

The internal detype function takes an additional arguments dictating
whether it should be eager or lazy.
We introduce a new type of delayed `DAst.t` AST nodes and use it for
`glob_constr`.
Such type, instead of only containing a value, it can contain a lazy
computation too. We use a GADT to discriminate between both uses
statically, so that no delayed terms ever happen to be
marshalled (which would raise anomalies).
We also fix a regression in the test-suite:
Mixing laziness and effects is a well-known hell. Here, an exception
that was raised for mere control purpose was delayed and raised at a
later time as an anomaly. We make the offending function eager.

Incidentally, this fixes a printing bug in output/inference.v where the
displayed name of an evar was the wrong one because its type was not
evar-expanded enough.

The structure of the Context module was refined in such a way that:
- Types and functions related to rel-context declarations were put into the Context.Rel.Declaration module.
- Types and functions related to rel-context were put into the Context.Rel module.
- Types and functions related to named-context declarations were put into the Context.Named.Declaration module.
- Types and functions related to named-context were put into the Context.Named module.
- Types and functions related to named-list-context declarations were put into Context.NamedList.Declaration module.
- Types and functions related to named-list-context were put into Context.NamedList module.
Some missing comments were added to the *.mli file.
The output of ocamldoc was checked whether it looks in a reasonable way.
"TODO: cleanup" was removed
The order in which are exported functions listed in the *.mli file was changed.
(as in a mature modules, this order usually is not random)
The order of exported functions in Context.{Rel,Named} modules is now consistent.
(as there is no special reason why that order should be different)
The order in which are functions defined in the *.ml file is the same as the order in which they are listed in the *.mli file.
(as there is no special reason to define them in a different order)
The name of the original fold_{rel,named}_context{,_reverse} functions was changed to better indicate what those functions do.
(Now they are called Context.{Rel,Named}.fold_{inside,outside})
The original comments originally attached to the fold_{rel,named}_context{,_reverse} did not full make sense so they were updated.
Thrown exceptions are now documented.
Naming of formal parameters was made more consistent across different functions.
Comments of similar functions in different modules are now consistent.
Comments from *.mli files were copied to *.ml file.
(We need that information in *.mli files because that is were ocamldoc needs it.
It is nice to have it also in *.ml files because when we are using Merlin and jump to the definion of the function,
we can see the comments also there and do not need to open a different file if we want to see it.)
When we invoke ocamldoc, we instruct it to generate UTF-8 HTML instead of (default) ISO-8859-1.
(UTF-8 characters are used in our ocamldoc markup)
"open Context" was removed from all *.mli and *.ml files.
(Originally, it was OK to do that. Now it is not.)
An entry to dev/doc/changes.txt file was added that describes how the names of types and functions have changed.

The core is a "detyping" function for [closed_glob_constr]. Which interpretes the variable names according to the Ltac context, and apply the standard detyping procedure to typed terms in the closure.

but the internal representation dropped let-in.
Ideally, the internal representation of the "match" should use
contexts for the predicate and the branches. This would however be a
rather significant change. In the meantime, just a hack.
To do, there is still an extra @ in the constructor name that does not
need to be there.

contortions in internalization/externalization. It uses a fully typed
version of detyping, requiring the environment, to move from
primitive projection applications to regular applications of
the eta-expanded version. The kernel is unchanged, and only
constrMatching needs compatibility code now.

instances still to do). Using heuristics to name after the quantifier
name it comes. Also added a "sigma" to almost all printing functions.

With ocaml 4.01, the 'unused open' warning also checks the mli :-)
Beware: some open are reported as useless when compiling with camlp5,
but are necessary for compatibility with camlp4. These open are now
marked with a comment.

1. sorts.ml: A small file utility for sorts;
2. constr.ml: Really low-level terms, essentially kind_of_constr, smart
constructor and basic operators;
3. vars.ml: Everything related to term variables, that is, occurences
and substitution;
4. context.ml: Rel/Named context and all that;
5. term.ml: derived utility operations on terms; also includes constr.ml
up to some renaming, and acts as a compatibility layer, to be deprecated.

Meanwhile, a simplified interface is provided in loc.mli.
