a misc_argp_hidden version of the option, so that --help
and --version are not shown in the --help output used
by help2man to generate spot-x.7.

"simul-limit" option, and add two new cases to "simul"
for the two don't care simulation
* src/bin/man/ltl2tgba.x: Mention the new options.
* src/tgba/bddprint.cc, src/tgba/bddprint.hh: Add bdd_print_isop
that prints the bdd into a Irreductible Sum Of Product.
* src/tgbaalgos/dupexp.cc, src/tgbaalgos/dupexp.hh: Add a way to
know which states (in the input) is which (in the result).
* src/tgbaalgos/simulation.cc, src/tgbaalgos/simulation.hh: Add
the Don't Care Simulation and the Don't Care Iterated Simulation.
* src/tgbatest/ltl2tgba.cc, src/tgbatest/spotlbtt.test,
src/tgbatest/Makefile.am, src/tgbatest/sim.test: Test them.
* bench/ltl2tgba/algorithms, bench/ltl2tgba/README,
bench/ltl2tgba/algorithms: Add a way to bench the don't care
simulation.
* src/tgbaalgos/postproc.hh, src/tgbaalgos/postproc.cc: Honor the
"simul" option in the option_map.
(do_simul, do_degen): New method to wrap the algorithms that may be
altered via option_map.
* src/bin/man/ltl2tgba.x (simul): Document this option.
* src/tgbaalgos/sccfilter.cc: Compute useless variable SCC-wise, then
renumber the useful variables so that they can be shared between SCCs.
* src/tgbatest/sccsimpl.test, src/tgbatest/ltl2ta.test: Adjust test
cases.
* src/tgbaalgos/postproc.cc: Add an option_map parameter, and use to get
extra options to pass to the degeneralization algorithm.
* src/tgbaalgos/postproc.hh: Adjust prototype, and store Boolean
variables for degeneralize() options.
* src/bin/ltl2tgba.cc: Add a -x option to fill the option map, and pass
it to the postprocessor.
* src/bin/man/ltl2tgba.x: Document the three degeneralization options.
Because benchmark show that this option usually do not help.
* src/tgbaalgos/degen.hh, src/tgbatest/ltl2tgba.cc: Here.
* src/tgbaalgos/degen.hh: Document the new options.
When something like XFa & FXa is reduced, the subformulae XFa and FXa
are both rewritten separately to XFa, and then the vector of arguments
of the And operators, [XFa,XFa], is passed through a specialized loop
that searches of the form X(...) that can potentially be simplified with
some other terms. This loop converts the vector [XFa,XFa] into the set
{XFa,XFa}={XFa} and forgot to deal with the case where the insertion
would actually not add an existing subformula.
* src/ltlvisit/simplify.cc: Fix the code for Or, and And.
* src/ltltest/reduc0.test: New file, to test it.
* src/ltltest/Makefile.am (TESTS): Add it.
* src/ltltest/reduccmp.test: Add an extra test that does not
trigger the bug (because reduccmp.test uses more than basic
optimizations, and the implication-based simplifications are
already able to detect that XFa and FXa are equivalent).
* src/tgbaalgos/postproc.hh (run): Rename the first argument as
input_disown to help Swig.
* wrap/python/spot.i: Wrap spot::postprocessor.
* wrap/python/ajax/ltl2tgba.html, wrap/python/ajax/protocol.txt:
Add an option for nondeterministic monitor.
* wrap/python/ajax/spot.in: Honor the new option, and rewrite the
monitor production using postprocessor.
* src/tgbatest/ltl2tgba.cc: Calling tgbatest/ltl2tgba -M -O (which
makes no sense, but that is no reason) used the "minimized" variable
for two automata, overwriting one.
* wrap/python/spot.i: The python bindings did not know about
sba_explicit automata, causing memory leaks, and complaints from the
bdd_dict.
Enable LTL simplifications by default for ltl2tgba & ltl2tgta, and make
sure the ltl_simplifier_options are all false initially. Before this
patch --low/-r1 had the same effect as --medium/-r2 with respect to LTL
simplification.
* src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc (simplification_level): Set
to 3 by default.
* src/bin/common_r.cc: Disable all ltl_simplifier options initially.
This follows up on a mail from Sonali Dutta.
* src/tgba/bdddict.hh (assert_emptiness, ~bdd_dict): Better
documentation.
* src/tgba/formula2bdd.hh (formula_to_bdd): Mention
unregister_all_my_variables().
(bdd_to_formula): Complete the documentation.
* THANKS: Add Sonali Dutta.
* src/misc/formater.cc, src/misc/formater.hh (scan): New method.
(prime): Use it.
* src/bin/ltlcross.cc (translator_runner::translator_runner): Scan each
specification string, and report those missing an input or output
%-sequence.
* NEWS: Mention it.
