39aa0e13c1 Ugly fix for handling enumerated types when exporting to Controllable-Nbac.
To avoid cyclic module dependencies (that show up when trying to
compile, e.g, the generated C code), enumerated types declared in the
main program are now "moved" into the module containing the generated
controllers.

be21bf31d8 Insertion of call to controller(s) when exporting to Controllable-Nbac node.
To enable recovery of parameter and output ordering by `ctrl2ept', the
Controllable-Nbac generation procedure now declares a new module
dedicated to the encapsulation of the controller functions yet to be
synthesized.

Handling of type declarations are probably buggy.

e885f82e00 Bug correction/feature adding: abstraction within contracts
Allowing additional inputs from abstractions within contracts. Thus,
calling non-inlined subnodes is allowed, as well as operations on
non-Boolean inputs or states (in contracts).

10bdab4dc6 Exclusively use ocamlfind; source documentation generation.
- Stripped portions of `myocamlbuild{,_config}.ml' that seem useless
  when `-use-ocamlfind' is passed to ocamlbuild.

- Added some code in `myocamlbuild_config.ml' to be able to generate
  documentation by merging interface and implementation files.

8aeab651ce First draft for Controllable-Nbac format generation.
- CtrlNbac: new module for internal representation and output code for
  Controllable-Nbac format;

- CtrlNbacGen: translation into Controllable-Nbac of Minils nodes
  necessitating controller synthesis; the insertion of calls to
  controllers is not yet done, and the nodes are left unchanged.

8497bafa2e Minor but correction in sigali output.
- Translation to z3z now evaluates constant expressions instead of
  abstracting them. This non-feature could cause "false" synthesis
  failures due to non-translatable yet constant expressions possibly
  introduced by tomato (or manually), for instance `not false' in node
  `n' bellow:

    node n (a: bool) returns (ok: bool)
      contract assume true enforce ok with ()
    let
      ok = a or not false;
    tel

9db97de879 Bug correction in `Sigalimain.translate_eq'.
- In Sigalimain: untranslatable non-boolean expressions should not be
  added as inputs of the controller.

- Avoided some compiler warnings in the same module (with OCaml ≥ 4).

ef536f412d Added option -nosink (CS optimisation)
The -nosink option suppress the sink state of sigali equations.

This optimizes the controller synthesis, but work only
when the synthesis objective instantaneoulsy depends only
on the current state (and not on current inputs).

90dda27a3a Bug correction in Schedule_interf
Bug due to the fact that a variable can be "defined" and "read"
(in scheduling sense) by the same equation, without being a memory:
e.g., a clock defined as the result of a node application, together
with another result on this same clock.

Bug correction: basically removed the "assert false" on killed_vars,
decr_uses; do not count as "use" the self reads.

8815a2cd03 Better handling of clocks in memalloc
- We can do a better allocation if we take into
account 'when' in extvalues 
(test/good/memalloc_clocks.ept shows the
improvement)
- Fixed a bug with memalloc on records: if we 
translate:
o = { a with .f = u }
to
o = a; o.f = u
then we cannot share u and o.f
