Improve the way transitions are duplicated when preparing the turn-based
game for synthesis. The resulting arena should now be deterministic on
nodes owned by the environment. Also move the code to another file, so
that it is easier to test (e.g. in Python).
* bin/ltlsynt.cc: move the code
* spot/twaalgos/split.cc, spot/twaalgos/split.hh: move the code and
implement the improvements

Zielonka algorithm has been fixed and optimized.
It also now computes the strategy for both players.
* bin/ltlsynt.cc: Update calls to parity_game::solve()
* spot/misc/game.cc, spot/misc/game.hh: Implement the changes
* spot/priv/satcommon.cc, spot/priv/satcommon.hh: Make it possible to
set the log file without setting the environment variable. Adjust
print_log to take the input state and print it as a new column.
* spot/twaalgos/dtbasat.cc, spot/twaalgos/dtwasat.cc: Adjust all
calls to print_log. Fix log output for incremental approaches.
Prefer purge_unreachable_states() over stats_reachable(). Do

const.

logs as they contain timings.
This is adapted from a proposition in a paper by J. Esparza,
J. Křentínský, and S. Sickert, submitted to LICS'18. We should add
proper references to the code and documentation once that paper is
accepted.

a "gf-guarantee" option to decide whether to use the new translation.

* tests/python/except.py: Add a couple more tests.
spot::acc_cond::mark_t is implemented as a bit vector using a single
unsigned, and implicit conversions between mark_t and unsigned may be
confusing. We try to use the proper interface.

To ease debugging and testing, ltlsynt can output the synthesized
strategy as an automaton, not just an aiger circuit.
Also, its exit code has been changed to something meaningful.
* bin/ltlsynt.cc: Various improvements: options, exit code, code style
* spot/twaalgos/aiger.hh, spot/twaalgos/aiger.cc,

* tests/Makefile.am: Add the test file to the test suite
* NEWS: document the new aiger printer
* doc/org/concepts.org: document the named property "synthesis-outputs",

This is not optimal yet because it still construct a minimal WDBA
internally, but it's better than the previous way to call
minimize_obligation() since it can avoid constructing the minimized
automaton in a few more cases.
* spot/tl/hierarchy.cc, spot/tl/hierarchy.hh: Introduce
is_obligation().
* bin/ltlfilt.cc: Wire it to --obligation.
* spot/twaalgos/minimize.cc: Implement is_wdba_realizable(),

This is long overdue, and we probably want to use tls-impl=1 in
ltlsynt.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh:
Add support for tls-impl=N.
* tests/core/ltl2tgba.test: Test it.
* bin/spot-x.cc, NEWS: Document it.
* spot/twaalgos/sccinfo.hh, spot/twaalgos/sccinfo.cc: Add an optional

detect useless SCCs and remove them.

that appeared in some tools.

* bin/README: Add a new paragraph about this.
* bin/autcross.cc, bin/ltlcross.cc: Move the
output options in their own section.

parity game followed by Calude et al.'s reduction from parity game to
reachability game.
