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
mospliter was ignoring event_univ unless favor_event_univ was set, (2)
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.

Adds the method spot::acc_cond::is_streett_like() that behaves like
spot::acc_cond::is_streett() except that it works on a wider range
of acceptance conditions, called Streett-like. Also adds
spot::acc_cond::streett_like_pairs() that returns a boolean assessing
whether the acceptance condition is Streett-like and also returns all
the Streett_like pairs.
Defines the new struct type spot::acc_cond::rs_pair.
Similarily, Adds the methods spot::acc_cond::is_rabin_like() and
spot::acc_cond::rabin_like_pairs().
* NEWS: Mention this modification

edge), and it was not properly iterating over the entire reachable
automaton.
