game: git rid of the parity_game class

Browse source 
This class was a simple wrapper on top of twa_graph_ptr, but it's
easier to simply use a twa_graph_ptr with a "state-player" property
instead, this way we will be able to modify the automata I/O routines
to support games directly.

* spot/misc/game.cc, spot/misc/game.hh: Rewrite the solver and
pg_printer interface.
* bin/ltlsynt.cc: Adjust.
* NEWS: Mention this change.
* doc/org/concepts.org: Mention the state-player property.

@ -1144,6 +1144,7 @@ Here is a list of named properties currently used inside Spot:
| ~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 |
| ~state-player~ | ~std::vector<bool>~ | the automaton represents a two-player game, and the vector gives the player (0 or 1) associated to each state |
| ~synthesis-outputs~ | ~bdd~ | conjunction of controllable atomic propositions (used by ~print_aiger()~ to determine which propositions should be encoded as outputs of the circuit) |
