This work makes it possible to take advantage of a compact
representation for integers in the entire system, as opposed to only
in some reduction machines. It is useful for heavily computational
applications, where even constructing terms is not possible without such
a representation.
Concretely, it replaces part of the retroknowledge machinery with
a primitive construction for integers in terms, and introduces a kind of
FFI which maps constants to operators (on integers). Properties of these
operators are expressed as explicit axioms, whereas they were hidden in
the retroknowledge-based approach.
This has been presented at the Coq workshop and some Coq Working Groups,
and has been used by various groups for STM trace checking,
computational analysis, etc.

This prevents the existence of a few naked pointers to C heap from the OCaml
heap. VM bytecode is represented as any block of size at least 1 whose first
field points to a C-allocated string.
This representation is compatible with the Coq VM representation of
(potentially recursive) closures, which are already specifically tailored
in the OCaml GC to be able to contain out-of-heap data.

Apparently Cysmtable.set_global_boxed is unused,
and removing it allows to get rid of a bunch of C code
concerning "boxed" things (including ACCUMULATECOND
instruction).
Still TODO: Csymtable.set_transparent_const and
Csymtable.set_opaque_const appear to be no-ops.
Should we remove them ?

...with proper options for dynamic loading of C stubs. I believe this
is the preferred way of compiling C stubs. It also adds by itself
-fno-defer-pop, -Wall, -I `ocamlc -where`, so CFLAGS could also be
simplified.

- essai de suppression des dependances debiles. (echec)
- Application des patch debian.
Pour ring et field :
- introduciton de la function de sign et de puissance.
- Correction de certains bug.
- supression de ring_replace ....
Pour exact_no_check :
- ajout de la tactic : vm_cast_no_check (t)
qui remplace "exact_no_check (t<: type of Goal)"
(cette version forcais l'evaluation du cast dans le
pretypage).
