This implementation of direct simulation was only working on degeneralized automata, and produce automata that are inferiors to those output by the new direct simulation implementation (in tgba/simulation.hh) which can also work on TGBA. The delayed simulation has never been reliable. It's time for some spring cleaning. * src/tgba/tgbareduc.hh, src/tgba/tgbareduc.cc: Delete. * src/tgba/Makefile.am: Adjust. * src/tgbaalgos/reductgba_sim.cc, src/tgbaalgos/reductgba_sim.hh: Remove all code, and keep only a deprecated replacement from reduc_tgba_sim(). * src/tgbaalgos/reductgba_sim_del.cc: Delete. * src/tgbaalgos/Makefile.am: Adjust. * src/tgbatest/reduccmp.test, src/tgbatest/reductgba.cc, src/tgbatest/reductgba.test: Delete. * src/tgbatest/Makefile.am: Adjust. * src/tgbatest/ltl2tgba.cc: Undocument options -R1s, -R1t, -R2s, -R2t, and implement them using the new direct simulation. Remove options -Rd and -RD. * src/tgbatest/spotlbtt.test: Remove entry using these old options. * wrap/python/spot.i: Do not process tgbaalgos/reductgba_sim.cc.
