* 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.

automata by removing useless trivial SCCs.

Annotate pools with valgrind macros so that it detects errors in pool

Related to issue #351.

* spot/twaalgos/sccfilter.cc: When handling weak automata, we know
they are very-weak if the SCC count is equal to the number of states.

... instead of inherently-weak.  The reason they were tagged
as inherently-weak is historical: this property was introduced
1.5 years before the weak propery.

Fixes #351.

* spot/twaalgos/ltl2tgba_fm.cc: Use prop_weak() instead of
prop_inherently_weak().  Also be more conservative about the use of
single_acc when unambiguous automata are generated.

Part of issue #351.

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.

* tests/core/ltl2tgba2.test, tests/core/ltl3ba.test: Add test cases.

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.
