add a --check=stutter-sensitive-example option

Browse source 
* spot/twaalgos/stutter.cc,
spot/twaalgos/stutter.hh (check_stutter_invariance): Add a
find_counterexamples argument.
* spot/twaalgos/hoa.cc: Output accepted-word and rejected-word examples.
* bin/common_aoutput.cc: Handle --check=stutter-sensitive-example.
* NEWS: Mention it.
* tests/core/stutter-tgba.test: Test it.
* doc/org/concepts.org, doc/org/hoa.org: Document accepted-word and
rejected-word named properties.
* bin/man/spot-x.x: Mention that --check=stutter-sensitive-example
ignores SPOT_STUTTER_CHECK.

| key name | (pointed) value type | description |
|---------------------+--------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------|
| ~accepted-word~ | ~std::string~ | a word accepted by the automaton |
| ~automaton-name~ | ~std::string~ | name for the automaton, for instance to display in the HOA format |
| ~product-states~ | ~const spot::product_states~ | vector of pairs of states giving the left and right operands of each state in a product automaton |
| ~original-states~ | ~std::vector<unsigned>~ | original state number before transformation (used by some algorithms like =degeneralize()=) |
| ~original-clauses~ | ~std::vector<unsigned>~ | original DNF clause associated to each state in automata created by =dnf_to_streett()= |
| ~state-names~ | ~std::vector<std::string>~ | vector naming each state of the automaton, for display purpose |
| ~degen-levels~ | ~std::vector<unsigned>~ | level associated to each state by the degeneralization algorithm |
| ~highlight-edges~ | ~std::map<unsigned, unsigned>~ | map of (edge number, color number) for highlighting the output |
| ~highlight-states~ | ~std::map<unsigned, unsigned>~ | map of (state number, color number) for highlighting the output |
| ~incomplete-states~ | ~std::set<unsigned>~ | set of states numbers that should be displayed as incomplete (used internally by ~print_dot()~ when truncating large automata) |
| ~degen-levels~ | ~std::vector<unsigned>~ | level associated to each state by the degeneralization algorithm |
| ~original-clauses~ | ~std::vector<unsigned>~ | original DNF clause associated to each state in automata created by =dnf_to_streett()= |
| ~original-states~ | ~std::vector<unsigned>~ | original state number before transformation (used by some algorithms like =degeneralize()=) |
| ~product-states~ | ~const spot::product_states~ | vector of pairs of states giving the left and right operands of each state in a product automaton |
| ~rejected-word~ | ~std::string~ | a word rejected by the automaton |
| ~simulated-states~ | ~std::vector<unsigned>~ | map states of the original automaton to states if the current automaton in the result of simulation-based reductions |
| ~state-names~ | ~std::vector<std::string>~ | vector naming each state of the automaton, for display purpose |
| ~synthesis-outputs~ | ~bdd~ | conjunction of controllable atomic propositions (used by ~print_aiger()~ to determine which propositions should be encoded as outputs of the circuit) |
Objects referenced via named properties are automatically destroyed
when the automaton is destroyed, but this can be altered by passing a
custom destructor as a third parameter to =twa::set_named_prop()=.
