With a minimal diff (so I'm not putting quotes ` ` around all the code).

And remove old French part.
And move part about the plugin API to the right section.

db_printers just isn't used.
api.txt is superseded by the API OCaml interface.

This gives syntax highlighting in Coq-aware editors.

Minor clean up, no sense in having these as they do nothing.

Indeed, "forall x, op x x = x" in not in the list, while this is one
of the two standard meanings of idempotence. So, knowing that x, y,
... and not n are used elsewhere for variables names, and elt for
constants. Moreover, it is probable that before using consistently x,
y and z, I had also used m and n, sometimes. So, a convergent
probability that it is (just) a typo.

This should help preventing weird compilation failures due to leftover
object files after deleting or moving some source files
By the way:
- use plain $(filter-out ...) instead of a 'diff' macro (thanks Jason
for the suggestion)
- rename FIND_VCS_CLAUSE into FIND_SKIP_DIRS since it contains more
than version control stuff nowadays

This is necessary in order for clients to identify the results of
queries. This is a minor breaking change of the protocol, affecting
only this particular call.
This change is necessary in order to fix bug ####.

Always output a warning on stderr when a deprecated option is used.

This exports two functions:
- declare_reduction_effect: to declare a hook to be applied when some
constant are visited during the execution of some reduction functions
(primarily cbv, but also cbn, simpl, hnf, ...).
- set_reduction_effect: to declare a constant on which a given effect
hook should be called.
Developed jointly by Thomas Sibut-Pinote and Hugo Herbelin.
Added support for printing effect in functions of tacred.ml.

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.

Constrintern.pf_global returns a global_reference, not a constr,
adapt plugins accordingly, properly registering universes where
necessary.

This is the continuation of #244, we now deprecate `CErrors.error`,
the single entry point in Coq is `user_err`.
The rationale is to allow for easier grepping, and to ease a future
cleanup of error messages. In particular, we would like to
systematically classify all error messages raised by Coq and be sure
they are properly documented.
We restore the two functions removed in #244 to improve compatibility,
but mark them deprecated.

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.

Inspired by https://coq.inria.fr/bugs/show_bug.cgi?id=5229 , which
this PR solves, I propose to remove support for non-synchronous
options.
It seems the few uses of `optsync = false` we legacy and shouldn't
have any impact.
Moreover, non synchronous options may create particularly tricky
situations as for instance, they won't be propagated to workers.

This fixes an inconsistency introduced in 554a6c806 (svn r12603) where
both interp_constr_with_bindings and interp_open_constr_with_bindings
were going through interp_open_constr (no type classes so as to not to
commit too early on irreversible choices, accepting unresolved holes).
We fix this by having interp_constr_with_bindings going to
interp_constr (using type classes and failing on unresolved evars).
The external impact is that any TACTIC EXTEND which refers to
constr_with_binding has now to decide whether it intends it to use
what the name suggest (using type classes and to fail if evars remain
unresolved), thus keeping constr_with_binding, or the actual behavior
which requires to use open_constr_with_bindings for strict
compatibility.
