In particular, the unused lib/tlm.ml and lib/gset.ml are removed
In addition, to simplify code, Libobject.record_object returning only the
('a->obj) function, which is enough almost all the time.
Use Libobject.record_object_full if you really need also the (obj->'a).

Cf. coqdev for the details of the bug report.
- Protect some Hashtbl.find and other risky functions in order to avoid
as much as possible to end with an irritating Anomaly : Not_found.
- Re-enable in pp_ocaml_extern the case of a module-file used as
a module (e.g. module A' := A for A.v) when doing modular extraction.
- Rework the code that decides to "open" or not modules initially:
opening A when A contains a submodule B hides the file B even when
B isn't opened itself, we avoid that now.
- Fix some tables (sets or maps) used by extraction for which it is
critical to consider constants/inductives/global_reference _not_
modulo the equivalence of Elie, but rather via Pervasives.compare.
Still to do : avoid appearance of '_a in extracted code.

Extraction under modules is highly experimental, and just work a bit.
Don't expect too much of it. With this commit, I simply avoid a few
"assert false" to occur when we are under modules. But things are
still quite wrong, for instance with:
Definition foo.
Module M.
Definition bar := foo.
Recursive Extraction bar.
Extraction of bar is ok, but foo isn't displayed, since extraction
can't get it: Lib.contents_after doesn't mention it, it is probably
in some frozen summary.

The auto-inlining has always been cumbersome. We only keep the
inlining of recursors (foo_rect for inductive foo), and a short
list of specific constants declared in mlutil.ml. In particular
we inline andb and orb to keep their lazy behavior.
The previous behavior is available via Set Extraction AutoInline

And similarly for Haskell: we do not force capitalized/uncapitalized
filenames anymore, but we rather follow the name of the .v file (with
new extensions of course). Ok, this is an incompatible change, but
it is really convenient, some people where actually already doing
some hacks to have this behavior (cf. Compcert).

- MPbound can be part of visible_mps (when printing the type of
a module parameter, or when printing body of a With), hence
the locality test base_mp mp = base_mp (top_visible_mp ())
isn't accurate.
- new organisation, pp_ocaml_gen is splitted in many sub-functions,
attempt to be clearer
- the shortcut (if List.length ls = 1 then ...) isn't safe,
we might detect name conflict even in this case.

- Add module parameters in the structure of visible_layer,
in order for module params to be part of name clash detection,
avoiding this way a source of potentially wrong code.
- In case of clash, module params are alpha-renamed to something
unique (Foo__XXX where XXX is the number contained in the mbid).
This solves some situations that were unsupported by extraction.
for instance the "Module F (X:T). Module X:=X. ... End F."
- We now check in Coq identifiers the presence of the
extraction-reserved string __. If it is found, we issue a warning
(which might become an error someday).

For instance:
Extract Inductive nat => int [ "0" "succ" ]
"(fun fO fS n => if n=0 then fO () else fS (n-1))".
See Extraction.v for more details and caveat.

The command : Extraction Implicit foo [1 3].
will tell the extraction to consider fst and third arg of foo as implicit,
and remove them, unless a final occur-check after extraction shows they
are still there. Here, foo can be a inductive constructor or a global
constant.
This allow typicaly to extract vectors into usual list :-)

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

* An inductive constructor Dummy instead of a constant dummy_name
* The Tmp constructor indicates that the corresponding MLlam or
MLletin is extraction-specific and can be reduced if possible
* When inlining a glob (for instance a recursor), we tag some
lambdas as reducible. In (nat_rect Fo Fs n), the head lams of
Fo and Fs are treated this way, in order for the recursive call
inside nat_rect to be correctly pushed as deeper as possible.
* This way, we can stop allowing by default linear beta/let
reduction even under binders (can be activated back via
Set Extraction Flag).
* Btw, fix the strange definition of non_stricts for (x y).

1- Management of the name-space in a modular development / sharing of non-logical objects.
2- Performance of atomic module operations (adding a module to the environment, subtyping ...).
1-
There are 3 module constructions which derive equalities on fields from a module to another:
Let P be a module path and foo a field of P
Module M := P.
Module M.
Include P.
...
End M.
Declare Module K : S with Module M := P.
In this 3 cases we don't want to be bothered by the duplication of names.
Of course, M.foo delta reduce to P.foo but many non-logical features of coq
do not work modulo conversion (they use eq_constr or constr_pat object).
To engender a transparent name-space (ie using P.foo or M.foo is the same thing)
we quotient the name-space by the equivalence relation on names induced by the
3 constructions above.
To implement this, the types constant and mutual_inductive are now couples of
kernel_names. The first projection correspond to the name used by the user and the second
projection to the canonical name, for example the internal name of M.foo is
(M.foo,P.foo).
So:
*************************************************************************************
* Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values *
*************************************************************************************
Map and Set indexed on names are ordered on user name for the kernel side
and on canonical name outside. Thus we have sharing of notation, hints... for free
(also for a posteriori declaration of them, ex: a notation on M.foo will be
avaible on P.foo). If you want to use this, use the appropriate compare function
defined in name.ml or libnames.ml.

No more time explosion (i hoppe) when using modules i have re-implemented atomic
module operations so that they are all linear in the size of the module. We also
have no more unique identifier (internal module names) for modules, it is now based
on a section_path like mechanism => we have less substitutions to perform at require,
module closing and subtyping but we pre-compute more information hence if we instanciate
several functors then we have bigger vo.
Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions
above, i will work on it soon...

(uniformisation of function names, classification). One of the most
visible change is the renaming of section_path into full_path (the
use of name section was obsolete due to the module system, but I
don't know if the new name is the best chosen one - especially it
remains some "sp" here and there).
- Simplification of the interface of classify_object (first argument dropped).
- Simplification of the code for vernac keyword "End".
- Other small cleaning or dead code removal.

- add coqtop option "-compat X.Y" so as to provide compatibility with
previous versions of Coq (of course, this requires to take care of
providing flags for controlling changes of behaviors!),
- add support for option names made of an arbitrary length of words
(instead of one, two or three words only),
- add options for recovering 8.2 behavior for discriminate, tauto,
evar unification ("Set Tactic Evars Pattern Unification", "Set
Discriminate Introduction", "Set Intuition Iff Unfolding").
