Improve memory allocation about Signal states.
Returning to Signal states map avoiding hole in vector allocation as we did not know how many state a Signal can takes. So a map may be a better choice Will see. Change-Id: Ie3ccdbd31296c5c0ebaefc109e75f2e0cde03756 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
