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
* tests/Makefile.am, tests/python/split.py: test it
* tests/core/ltlsynt.test: update existing tests to reflect the changes
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
Reported by Simon Jantsch and David Müller.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite wihtout assuming
that the product of two accepting SCCs is accepting, Also use
the result of is_accepting_scc()/is_rejectng_scc() when available.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh: Make it
possible to check the acceptance of a unique SCC.
* tests/core/unambig.test: Add more test cases.

Fixes#327.
* spot/twaalgos/dot.cc: Emit a tooltip="..." for state names and
labels that are disabled by option "1".
* doc/org/tut51.org, tests/python/product.ipynb, NEWS: Discuss this.
* tests/core/readsave.test, tests/python/alternation.ipynb,
tests/python/automata.ipynb: Adjust test cases.
This is needed so that SVG files are included as an <object...> rather
than as an <img...>, which in turn is needed to ensure SVG tooltips
will work. We do not explicitly require org-mode 9.1, but we install
it if it is not present.
* HACKING: Mention the requirement.
* doc/org/.dir-locals.el.in, doc/org/init.el.in, doc/org/spot.css:
Adjust to org-mode 9.1.
* doc/Makefile.am: Run emacs with the site-lisp libraries, in
case it contains a more recent org-mode.
* elisp/ob-dot.el: Delete, this was a work around older versions.
* elisp/Makefile.am: Adjust.
Fixes#341.
* python/spot/__init__.py (automata): Rewrite and simplify using
the subprocess context manager.
* tests/python/341.py: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention the issue.

* NEWS: Mention the issue.
* 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
not call scc_filter() on colored automata.
* spot/twaalgos/dtwasat.hh: Document the new "log" option.
* NEWS: Mention the changes.
* tests/python/satmin.ipynb: New file.
* tests/Makefile.am: Add it.

bench/dtgbasat/tabl1.pl, bench/dtgbasat/tabl2.pl,
bench/dtgbasat/tabl3.pl, bench/dtgbasat/tabl4.pl: Adjust for
the new column.
* spot/misc/satsolver.cc, spot/misc/satsolver.hh (stats): Make it
const.
* python/spot/__init__.py (sat_minimize): Add display_log and
return_log options.
* tests/python/ipnbdoctest.py: Adjust to not compare SAT-minimization
logs as they contain timings.

the input if it is already co-Büchi.
* tests/core/dca.test: Test this.

* spot/twaalgos/langmap.cc, spot/ltsmin/ltsmin.cc: Add asserts to hide
spurious "potential null pointer dereference" messages.
* spot/twaalgos/tau03opt.cc (color_ref): Initialize pc to nullptr
even when is_cyan is true so that valgrind does not report pc being
used uninitialized in is_white().
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.
* spot/twaalgos/gfguarantee.cc, spot/twaalgos/gfguarantee.hh:
New files.
* spot/twaalgos/Makefile.am, python/spot/impl.i: Add them.
