hoa: output acc-name for several acceptance types
So far the HOA output would emit an acc-name only for generalized-Buchi or inferior types (Buchi, all). It now knows about none, co-Buchi, generalized-co-Buchi, Rabin, Streett, and generalized-Rabin as well. * src/twa/acc.cc, src/twa/acc.hh: Add detection code. * src/twaalgos/hoa.cc: Use it. * src/tests/remfin.test, src/tests/maskacc.test, src/tests/complete.test, src/tests/sim3.test, src/tests/ltl2dstar.test: Adjust tests. * src/tests/hoaparse.test: Adjust and add more tests.
