621fb818e3 improve translation of ms-phi-h=2..3
* spot/twaalgos/gfguarantee.cc: Rework the history computation to keep
an overapproximation of the history, and a longer one.  Also replay
the history even if there is no initial trivial SCC.  This helps with
translating FG(!a|XXXb) where we need to keep the history of a, but we
were previously unable to do so because some state had both "a" and
"ab" as input.

7e9325866f gf_guarantee_to_ba: save states using histories
This improves gf_guarantee_to_ba() on formulas GF(φ) where the
automaton for F(φ) as several leading transiant SCCs.  E.g.,
GF(a <-> XXXa) where we know get results that are as good as
those of delag without loosing on the cases where delag's technique
would actually produce two big automata.

730c6bbca2 minimize_wdba: use a product to decide accepting SCCs
Fixes #347.

* spot/twaalgos/minimize.cc, spot/twaalgos/minimize.hh: An SCC of the
determinized automaton is marked as accepting if it intersects any
accepting SCC of the original automaton.  This can be checked by
making a product.  As a consequence the output of minimize_wdba() now
always includes the original language, and minimize_obligation() only
needs a single containment check.
