* 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.
