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,
  spot/twaalgos/Makefile.am: Move the aiger printer to separate files
* tests/core/ltlsynt.test: Clean up and update test file
* 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",
  used by print_aiger

* doc/Makefile.am (dist-hook): Remove.
* HACKING: Adjust.

Fixes #307.

* spot/tl/formula.hh: Here.
* tests/python/ltlparse.py: Test it.
* NEWS: Mention it.

Fixes #299.

* configure.ac, doc/Makefile.am: Adjust.
* NEWS, HACKING, README: Document the change.
* doc/dot.in: Delete, not used anymore.
* doc/Doxyfile.in: Adjust to not look for dot.
* debian/rules: Use --enable-doxygen.

* tests/python/ipnbdoctest.py: Here.  It seems importlib
does not load importlib.util anymore.

* tests/python/dca.test: Do not assume the run script is in the source
directory.

Suggested in #299.

doc/org/tut51.org: Adjust all dot outputs to produce svg.
* doc/org/arch.tex, doc/org/hierarchy.tex, doc/org/satmin.tex: Adjust
to produce a pdf with 12pt text.
* doc/Makefile.am: Adjust the generation of arch.svg, hierarchy.svg,
and satmin.svg: From above.
* doc/org/.dir-locals.el.in, doc/org/init.el.in: Adjust dot arguments
to produce svg with 12pt text (the default was 14pt).
* doc/org/spot.css: Use Lato as the main font for consistency with
automata.
* HACKING: pdf2svg is now required to build the doc.

Suggested in #299.

* doc/Doxyfile.in: Here.

* tests/sanity/namedprop.test: fix typo for proper output

* spot/tl/hierarchy.cc: Rewrite is_recurrence(), is_persistence()
* spot/tl/hierarchy.hh: Fix typo.
* tests/core/hierarchy.test: Add tests.

* NEWS: Mention the bug.

This only occurs when doing the emptiness check of twa with allocated
states.

* spot/twaalgos/couvreurnew.cc: Here.
* NEWS: Mention the bug.

* spot/misc/bddlt.hh: do it

* spot/misc/game.cc: here.

* spot/misc/game.cc: here.

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(),
needed by the above.
* tests/core/obligation.test: Test it.
* bin/man/spot-x.x, NEWS: Document it.

* spot/tl/hierarchy.cc: code was actually reachable.

* spot/twaalgos/minimize.cc (minimize_obligation): When
needed (i.e. in the non-deterministic case), make the reverse check
before the forward check, because it does not require translating the
negated formula.

* spot/twaalgos/minimize.cc (wdba_minimization): Here.

* spot/twaalgos/minimize.cc (wdba_minimization): Improve handling of
deterministic input by not doing the powerset/wdba_scc_is_accepting
duo, and skipping the one inclusion test.

* spot/twaalgos/couvreurnew.cc: explicit operator bool is not used by
return.

* bin/dstar2tgba.cc: Do not call to_generalized_buchi(), it's
already done in postproc.

* bin/common_setup.cc: Here.
* NEWS, bin/man/spot-x.x: Document it.

Fixes #296.

* doc/org/ltlcross.org: Here.

* configure.ac, NEWS: Here.

* NEWS, configure.ac, doc/org/setup.org: Update.

That's the new name of ltl3hoa.

* bin/common_trans.cc: Add it.

Fixes #297. Implement the following rules.

Fin(i) & Fin(j) by f if i and j are complementary
Fin(i) & Inf(i) by f
Inf(i) | Inf(j) by t if i and j are complementary
Fin(i) | Inf(i) by t.

* spot/twaalgos/cleanacc.cc, spot/twaalgos/cleanacc.hh: Here.
