There is not need to re-export Gramlib's API in a non-structured way
anymore. We thus expose the core Gramlib interface to users and remove
redundant functions.
A question about whether to move more parts of the API to `Gramlib` is
still open, as well as on naming.

|
We remove Coq's wrapper over gramlib's grammar constructors.

After the gramlib merge and the type-safe interface added to it, the
grammar extension type is redundant; we thus make it private as a
first step on consolidating it with the one in gramlib's.

Four types of numerals are introduced:
- positive natural numbers (may include "_", e.g. to separate thousands, and leading 0)
- integer numbers (may start with a minus sign)
- positive numbers with mantisse and signed exponent
- signed numbers with mantisse and signed exponent
In passing, we clarify that the lexer parses only positive numerals,
but the numeral interpreters may accept signed numerals.
Several improvements and fixes come from Pierre Roux. See
https://github.com/coq/coq/pull/11703 for details. Thanks to him.

Add headers to a few files which were missing them.

We reuse the same type as for options, even though it is a bit ill-named. At
least it allows to share code with it.

The current implementation was seemingly never thought for this kind of
semantics. Everything is superglobal by construction, notably hint database
creation and naming schemes. The new mode feels a bit hackish to me, at
some point this should be fully reimplemented from scratch with a clear
design in mind.

Since tclOR/tclORELSE are not supposed to return critical exceptions,
we don't need to replace catchable_exception by noncritical.

This fixes #11547 ; note that it is hard to register such handlers in
the `Summary` due to layering issues; there are potential anomalies here
depending on how plugins do register their data structures.

We make the primitives for backtrace-enriched exceptions canonical in
the `Exninfo` module, deprecating all other aliases.
At some point dependencies between `CErrors` and `Exninfo` were a bit
complex, after recent clean-ups the roles seem much clearer so we can
have a single place for `iraise` and `capture`.

This is to be consistent with "pose (x:=a)" (and an alternative to
"assert (x:=a)").
This was suggested by
"https://github.com/HoTT/HoTT/pull/1208#discussion_r374342962".

It was not documented, I do not think it is used in the wild, and it relies
on legacy code. As solid conjunction of reasons that support its deprecation.

This was redundant with `iraise`; exceptions in the logic monad now
are forced to attach `info` to `Proofview.NonLogical.raise`

Also renamed it to relative_entry_level.
Correspondence between old and new representation is:
(n,L) -> LevelLt n
(n,E), (n,Prec n) -> LevelLe n
(n,Any) -> LevelSome
(n,Prec p) when n<>p was unused
Should not change global semantics (except error message in pr_arg).

This PR is in preparation of #9067 (together with #11647) .
Before this PR, `grammar_extend` always took an optional `reinit`
argument, even if it was never set to `Some ...`. Indeed, there is a
single case where reinit is needed; we track it now by using a
different extension rule constructor.

It's been ignored since the introduction of universe polymorphism.

Currently, `.v` under the `Coq.` prefix are found in both `theories`
and `plugins`. Usually these two directories are merged by special
loadpath code that allows double-binding of the prefix.
This adds some complexity to the build and loadpath system; and in
particular, it prevents from handling the `Coq.*` prefix in the
simple, `-R theories Coq` standard way.
We thus move all `.v` files to theories, leaving `plugins` as an
OCaml-only directory, and modify accordingly the loadpath / build
infrastructure.
Note that in general `plugins/foo/Foo.v` was not self-contained, in
the sense that it depended on files in `theories` and files in
`theories` depended on it; moreover, Coq saw all these files as
belonging to the same namespace so it didn't really care where they
lived.
This could also imply a performance gain as we now effectively
traverse less directories when locating a library.

The standard use is to repeat the option keywords in lowercase, which
is basically useless.

Namely, Evd.evar_env and Evd.evar_filtered_env now take an additional
environment instead of querying the imperative global one. We percolate
this change as higher up as possible.

There are no users in Coq but maybe some plugin wants it so don't
completely remove it

Some calls are actually guarded by a check that the scheme is already in
the cache. There is no reason to generate dummy side-effects in that case.

This allows to give access to all printing options (e.g. a scope or
