These two functions were doing almost identical work, the only
difference was the way to select the SCC to keep. Now we have a more
uniform way to do that. Closes#172.
* bin/autfilt.cc: Offer a unique --decompose-scc option, but keep
--decompose-strength as an alias for backward compatibility.
* spot/twaalgos/strength.cc, spot/twaalgos/strength.hh: Rename
decompose_strength as decompose_scc, and handle a way to list
all SCC numers in the string specifier. This gets rid
of the nearly identical

test cases.

twa_sub_statistics when %t is not used.

the function.

The libtool version distributed by Debian is patched to *not* propagate
dependencies (i.e., if libA depends on libB, then linking against libA
will not automatically link against libB, it has to be explicit),
contrary to what the Libtool manual document. So now we explicitly
link against both libA and libB in such case.
* configure.ac: Remove the workaround that does not work for
MinGW.
* doc/org/compile.org: Mention the issue.
* bin/Makefile.am, tests/Makefile.am, spot/ltsmin/Makefile.am,
spot/gen/Makefile.am, doc/org/g++wrap.in: Make the dependencies
explicit.
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.
* tests/core/ltl2tgba.test: Add a new test case based on Maximilien's
report.
* tests/core/complement.test, tests/core/det.test,
tests/core/parseaut.test, tests/core/prodor.test, tests/core/scc.test,

is unregistered, do not wait for the dictionary's destruction. This
was the main culprit for #262.
* tests/core/ltl2tgba.test: Add test cases.
* NEWS: Mention the bug.
The cache used in formula simplification will keep atomic propositions
defined between several translations, and may impact variable order.

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.
* spot/tl/simplify.cc: Improve handling of the above points.
