hoa: output acc-name for several acceptance types

Browse source 
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.
