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
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.
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.
