Replace it by a new degeneralize_tba(), that use the same tricks as degeneralize(). * src/tgba/tgbatba.cc, src/tgba/tgbatba.hh: Delete. * src/tgba/Makefile.am: Adjust. * src/tgbaalgos/degen.cc, src/tgbaalgos/degen.hh: Implement a degeneralize_tba() function sharing its code with degeneralize(). * src/tgbatest/ltl2tgba.cc: Rename -D to -DT so that we can pass it the same option as -DS. * src/tgbatest/degenid.test, src/tgbatest/emptchk.test, src/tgbatest/emptchke.test, src/tgbatest/ltlcounter.test, src/tgbatest/ltlcross.test, src/tgbatest/spotlbtt.test, src/tgbatest/ltl2tgba.test: Adjust. * src/tgbatest/det.test, src/tgbatest/emptchk.test: Adjust numbers to the smaller output. * src/saba/sabacomplementtgba.cc, src/saba/sabacomplementtgba.hh, src/tgbaalgos/minimize.cc, src/tgbaalgos/neverclaim.cc, src/tgbaalgos/neverclaim.hh, src/tgbaalgos/postproc.cc, src/tgbatest/randtgba.cc, src/tgbatest/complementation.cc, wrap/python/spot.i, wrap/python/tests/ltl2tgba.py, src/sabatest/sabacomplementtgba.cc: Adjust to the removal of tgba_tba_proxy, using degeneralize_tba() if needed.
