* tests/core/ltl2dstar.test: Reduce the amount of tests performed on
one formula that is problematic for ltl2dstar.

Our use of
  ltl2tgba=ltl2tgba
  autfilt=autfilt
  ...
all over the test cases comes from the time where those tools were not
in PATH and we actually had something like
  ltl2tgba=../../bin/ltl2tgba
  autfilt=../../bin/autfilt

But today that is useless, and we prefer to write ltl2tgba rather than
$ltl2tgba, so let's remove this old cruft.

* tests/core/ltlsynt.test: Escape newlines and test PGsolver printer

* tests/python/ipnbdoctest.py: skip test when jupyter is not found

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/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

Fixes #307.

* tests/core/hierarchy.test: Add tests.

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.

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.
* tests/python/merge.py: Add more test cases.
* NEWS: Mention the change.

This improves the coverage for bdd_dict::assert_emptiness() and
bdd_dict::dump().

acc_cond::is_generalized_streett, acc_cond::operator==, and
acc_cond::operator!=.

* spot/twaalgos/stats.cc, spot/twaalgos/stats.hh,
bin/common_aoutput.cc, bin/common_aoutput.hh: plug %g and %G into
acc_cond::name() when arguments are given as %[arg]g.  or %[arg]G.
