game: reimplement parity game solving

Browse source 
* spot/misc/game.cc, spot/misc/game.hh: More efficient implementation
of Zielonka's algorithm to solve parity games.  Now supports SCC
decomposition and efficient handling of certain special cases.
* doc/org/concepts.org: Document "strategy" and "state-winner"
properties.
* bin/ltlsynt.cc, tests/python/paritygame.ipynb: Adjust.
* tests/core/ltlsynt.test: Add more tests.

| ~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 |
| ~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 |
| ~state-winner~ | ~std::vector<bool>~ | vector indicating the player (0 or 1) winning from this state |
| ~strategy~ | ~std::vector<unsigned>~ | vector representing the memoryless strategy of the players in a parity game. The value corrsponds to the edge number of the transition to take. |
| ~synthesis-outputs~ | ~bdd~ | conjunction of controllable atomic propositions (used by ~print_aiger()~ to determine which propositions should be encoded as outputs of the circuit) |
