09e47d648a decompose: merge decompose_strength() and decompose_scc()

9ab4b840fd simulation: do not depend on bdd numbers for ordering classes
Fixes #262 again.  Reported by Maximilien Colange.

* spot/twaalgos/simulation.cc: Use state numbers to order classes, not
their signatures.  The problem was that even if two simulation of the
same automaton assign the same signature, the BDD identifier used for
that signature might be different, and therefore the ordering obtained
by using BDDs as keys in a map can be different.  A side-effect of
this change is that the order of states in automata produced by
simulation-based reduction may change; many tests had to be updated.

report.

845958834f simplify: fix related to event_univ handling
Fixes #260.  Reported by František Blahoudek.

The simplification F(f)|q = F(f|q), where q designates an event_univ
formula, was not always applied because of a couple of issue: (1) the

when processing formulas from res_EventUniv they were not put back
into res_F or res_G to be subject to the F/G rules.
