c++11: introduce tgba::succ(s) to replace tgba::succ_iter(s).

Browse source 
| tgba_succ_iterator* i = aut->succ_iter(s);
| for (i->begin(); !i->done(); i->next())
|   {
|      // ...
|   }
| delete i;

becomes

| for (auto i: aut->succ(s))
|   {
|      // ...
|   }

hiding the begin()/done()/next() interface, taking care of the delete,
and allowing more optimization to come.

* src/tgba/succiter.hh, src/tgba/tgba.hh: Implement the above
new interface.
