Improving split and reorganizing

* spot/twaalgos/synthesis.cc, spot/twaalgos/synthesis.hh: New files
regrouping the functionnalities split and apply_strategy for synthesis
* python/spot/impl.i, spot/twaalgos/Makefile.am: Add them.
* spot/twaalgos/split.cc, spot/twaalgos/split.hh: No longer contains
the splits necessary for for synthesis, moved to
spot/twaalgos/synthesis.cc, spot/twaalgos/split.hh Split is now faster
and reduces the number of intermediate states, reducing the overall
size of the arena
* spot/misc/game.cc, spot/misc/game.hh: Renaming propagate_players to
alternate_players.
* tests/core/ltlsynt.test, tests/python/split.py: Update tests.
* bin/ltlsynt.cc: Adjust to new split. Swap order of split and
to_parity for lar.
