- move_location to proofs/logic.
- intro_pattern_naming to Namegen.

AFAICT this tactic is always used on ground terms.

When creating a scheme for bifinite inductive types, we do not create a
fixpoint.

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.

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.

Unfortunately OCaml doesn't deprecate the constructors of a type when
the type alias is deprecated.
In this case it means that we don't get rid of the kernel dependency
unless we deprecate the constructors too.

We'd like to handle proofs functionally we thus recommend not to use
printing functions without an explicit context.
We also adapt most of the code, making more explicit where the
printing environment is coming from.
An open task is to refactor some code so we gradually make the
`Pfedit.get_current_context ()` disappear.

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

This will allow to merge back `Names` with `API.Names`

This is a first step towards some of the solutions proposed in #6008.

ML level can set the flags themselves.
In particular, using injection and discriminate with option "Keep
Proofs Equalities" when called from "decide equality" and "Scheme
Equality".
This fixes bug #5281.

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).

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.

This module collects the functions of Nameops which are about Name.t
and somehow standardize or improve their name, resulting in particular
from discussions in working group.
Note the use of a dedicated exception rather than a failwith for
Nameops.Name.out.
Drawback of the approach: one needs to open Nameops, or to use long
prefix Nameops.Name.

We move Coqlib to library in preparation for the late binding of
Gallina-level references. Placing `Coqlib` in `library/` is convenient
as some components such as pretyping need to depend on it.
By moving we lose the ability to locate references by syntactic
abbreviations, but IMHO it makes to require ML code to refer to
a true constant instead of an abbreviation/notation.
Unfortunately this change means that we break the `Coqlib`
API (providing a compatibility function is not possible), however we
do so for a good reason.
The main changes are:
- move `Coqlib` to `library/`.
- remove reference -> term from `Coqlib`. In particular, clients will
have different needs with regards to universes/evar_maps, so we
force them to call the (not very safe) `Universes.constr_of_global`
explicitly so the users are marked.
- move late binding of impossible case from `Termops` to
`pretying/Evarconv`. Remove hook.
- `Coqlib.find_reference` doesn't support syntactic abbreviations
anymore.
- remove duplication of `Coqlib` code in `Program`.
- remove duplication of `Coqlib` code in `Ltac.Rewrite`.
- A special note about bug 5066 and commit 6e87877 . This case
illustrates the danger of duplication in the code base; the solution
chosen there was to transform the not-found anomaly into an error
message, however the general policy was far from clear. The long
term solution is indeed make `find_reference` emit `Not_found` and
let the client handle the error maybe non-fatally. (so they can test
for constants.

Now it is a private field, locations are optional.

The transition has been done a bit brutally. I think we can still save a
lot of useless normalizations here and there by providing the right API
in EConstr. Nonetheless, this is a first step.

- We avoid unnecessary use of Pp -> string conversion functions.
and the creation of intermediate buffers on logging.
- We rename local functions that share the name with the Coq stdlib,
this is usually dangerous as if the normal function is removed, code
may pick up the one in the stdlib, with different semantics.

Currently, the STM, vernac interpretation, and the toplevel are
intertwined in a mutual dependency that needs to be resolved using
imperative callbacks.
This is problematic for a few reasons, in particular it makes the
interpretation of commands that affect the document quite intricate.
As a first step, we split the `toplevel/` directory into two: "pure"
vernac interpretation is moved to the `vernac/` directory, on which
the STM relies.
Test suite passes, and only one command seems to be disabled with this
approach, "Show Script" which is to my understanding
obsolete. Subsequent commits will fix this and refine some of the
invariants that are not needed anymore.
