a0e97b82ea CtrlNbac backend: systematic sink state, outputs as local variables
Changes in CtrlNbac back-end :
- systematic sink state, only in ctrln code
- sink state "ok" removed (useless as was coded)
- no sink state in minils code
- outputs in ctrln are local variables, no longer state variables

69b8cc5a18 Added operator (=>) in Pervasives module
Operator (=>) for implication added in Pervasives module.

"a => b" is translated into "not a or b" at code generation.

d8d24ffd95 Handle modularity/several controllers by module
* Several controllers by module : added option "-m <Module>" in ctrl2ept

Generate controllers for each node of one module in <module>_controller.ept

* Types of <Module> no longer moved to <Module>_controller

* Added "_types" suffix for type dependencies for C target

0b7eba8458 Add error for non-stateful decls. in pervasives
Attempts to compile a pervasives.epi containing functions with multiple
outputs or nodes now fail with an informative error message.

* The following files demonstrate the problem:

  pervasives.epi:
    type bool = true | false
    external val node test(bool;bool) returns bool

  broken.ept:
    node broken() returns (y : bool)
    let
      y = test(false, false);
    tel

  Running:
    heptc -nopervasives pervasives.epi
    heptc -stdlib . -target c broken.ept

  Fails with:

    ---------
    Internal compiler error
    Passe : Static evaluation failed of the pervasive operator test
    ----------
    Fatal error: exception Misc.Assert_false

* A different error occurs for nodes that return multiple outputs:

  pervasives.epi:
    type bool = true | false
    external val node test(bool;bool) returns (bool;bool)

  broken.ept:
    node broken() returns (y : bool)
    var l1 : bool;
    let
      (y,l1) = test(false, false);
    tel

  Running:
    heptc -nopervasives pervasives.epi
    heptc -stdlib . broken.ept

  Gives:
    Inconsistent clock annotation for exp test(false, false).
    File "broken.ept", line 4, characters 11-29:
    >  (y,l1) = test(false, false);
    >           ^^^^^^^^^^^^^^^^^^
    Clock Clash: this expression has clock 'a3,
    but is expected to have clock ('a4 * 'a5).

  The name "test" is parsed as an Eextvalue (rather than an Eapp), and there
  is an implicit assumption in compiler/minils/analysis/clocking.ml that such
  values have a simple clock.

755b570a96 Correct typing of numericals when translating Controllable-Nbac nodes
Without this change one could end up with inconsistent numerical types
when expressions like 1 + xx /. 3.0 >= 0 (with xx being a float), that
is correctly handled in ReaTK's frontend, are translated into the
heptagon's internal representation.

74b94c9718 Fix handling of nodes without actual controllers by ctrl2ept
These changes allow to handle the case where contracts are only used
for verification purposes, in which case the functions generated by
ReaX have no outputs and are not functions stricto sensu.  Indeed, in
this case the new controller module still needs to be declared and
compiled as we may have re-qualified types during the generation of
the Controllable-Nbac code: we moved all types declared in the
original module into the controller module to break cyclic module
dependencies that would otherwise be introduced if the controller is
expressed using data of such types.

3dfbeffeb6 Added syntax for reachability and attractivity in contracts
Contracts can now comprise a list of objectives (in any order).

One objective can be (e being a Boolean heptagon expression) :
- invariance, with the syntax "enforce e"
- reachability, "reachable e"
- attractivity, "attractive e"

307f3d8418 Controllable-Nbac import&export now support relocation of alias types.
- Controllable-Nbac export (CtrlNbacGen): correct handling of float
  expressions, as well as alias types;

- Controllable-Nbac controller importer (CtrlNbacAsEpt): Declaration
  of enumerated types and aliases that are relocated to controller
  modules is now performed based on the interface.  Dependencies
  between type aliases are also taken into account now;

- ctrl2ept tool: correct loading of pervasives module.
