an ugly try ... with construct.

Why? : avoid catching (and probably ignoring) exceptions
such as Sys.Break, anomalies, assertions, leading to undetected
bugs and ignored Ctrl-C.
How? : when the precise exception(s) concerned by the try is
known, use them explicitely in the "with". Otherwise, let's use
the pattern "with e when Errors.noncritical e -> "
Particular case : when an exception is catched and reraised
immediately after some adjustments, we leave it untouched.
Simply, for easily identifying these situations later, the name
of the exception variable is changed to "reraise".
Please also adopt this coding style. Automatic checks based
on the "mascot" tool of X. Clerc will be runned regularly.
If you want to avoid to check a particular try...with, use
the variable name "any" after the "with".
All these changes have been tested using the standard library
and the test-suite, but unfortunately this is far from ensuring
that coqtop behaves as before. We'll see after the nightly bench...

Ok, this is merely a matter of taste, but up to now the usage
in Coq is rather to use capital letters instead of _ in the
names of inner modules.

For the moment, the compatibility names about these new modules
are still used in the rest of Coq.

the new Int module. Only the most obvious were removed, so there
are a lot more in the wild.
This may sound heavyweight, but it has two advantages:
1. Monomorphization is explicit, hence we do not miss particular
optimizations of equality when doing it carelessly with the generic
equality.
2. When we have removed all the generic equalities on integers, we
will be able to write something like "let (=) = ()" to retrieve all
its other uses (mostly faulty) spread throughout the code, statically.

List module. That way, an "open Util" in the header permits using
any function of CList in the List namespace (and in particular, this
permits optimized reimplementations of the List functions, as, for
example, tail-rec implementations.

Util only depends on Ocaml stdlib and Utf8 tables.
Generic pretty printing and loc functions are in Pp.
Generic errors are in Errors.

Too many "open Errors" on the contrary.

- An inductive is hidden inside case_info.
(btw, maybe we could get rid of this ci_ind altogether,
since the information is already in the predicate of the match)
- Typical situation where user kn and canonical kn are initially (==)
was not preserved by hconsing of constant / mutual_inductive
- inductive = (mutual_inductive * int) and
constructor = inductive * int were not properly shared
This should fix the strange situation of Udine/PiCalc taking *more*
vo space after the last round of hcons tweaks.

Now that Yann has provided a better hashing mechanism for constr,
it might be interesting to (re-?)activate a global hash-consing of
constr. Earlier, specific hash-cons tables were created at each call
to hcons_constant_declaration. According to Hugo, this was meant to
avoid blow-up in at least contrib Pocklington. This contrib seems
to behave nicely now with global hashconsing (thanks Yann ;-).
We'll see tomorrow what impact this has on other contribs.

- When hash-consing, seeing ident as having string as sub-structure
induces a penalty: two searchs are done in two tables
(one for string, one for id).
We simply say now that the hcons function for ident is the one
for string
- use more == during hash-consing of Names.uniq_ident and
Names.module_path
- clarification concerning hash-cons of Names.constant and
Names.mutual_inductive: we only hash-cons the canonical part,
but == could be used nonetheless on the obtained pair. Simply
note that canonical_con of hash-consed constants will produce
kernel_names that may be (=) but not (==).
- Code cleanup : no direct use of string hash-consing apart in Names,
we hence simplify hcons_names

Before this commit, when simpl was finding the constant name
for folding some (mutual) fixpoint, this was done via some
repr_con followed by make_con. Problem: this doesn't preserve
the canonical part of a Names.constant. For instance the following
script was buggish:
Module M.
Fixpoint foo n := match n with O => O | S n => bar n end
with bar n := match n with O => O | S n => foo n end.
End M.
Module N.
Include M. (* foo, bar have here "user name" N but "canonical name" M *)
Eval simpl in (fun x => bar (S x)).
(* Anomaly: uncaught exception Failure "Cannot print a global reference". *)
(* since simpl has produce a different bar with both user and canonical N *)
TODO : check all other uses of make_con in the rest of the sources...

In checker:
- delta_resolver inferred by the module system is checked through regular delta reduction steps
- the old mind_equiv field of mutual_inductive is simulated through a special table in environ
- small optimization, if the signature and the implementation of a module are physically equal
(always happen for the toplevel module of a vo) then the checker checks only the signature.
In kernel
- in names i have added two special equality functions over constant and inductive names for the checker,
so that the checker does not take in account the cannonical name inferred by the module system.

- 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

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.
2-
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...

This commit concerns about the first half of the useless code
mentionned by Oug for coqtop (without plugins). For the moment,
Oug is used in a mode where any elements mentionned in a .mli
is considered to be precious. This already allows to detect and
remove about 600 lines, and more is still to come.
Among the interesting points, the type Entries.specification_entry
and its constructors SPExxx were never used. Large parts of cases.ml
(and hence subtac_cases.ml) were also useless.

- Relaxed the validity check on identifiers from an error to a warning.
- Added a filtering option to Print LoadPath.
- Support for empty root in option -R.
- Better handling of redundant paths in ml loadpath.
