associate that transition to its high-level name.
* src/tgba/tgba.hh, src/tgba/tgba.cc (tgba::transition_annotation):
New method.

* src/tgbaalgos/replayrun.cc (print_annotation): New function.
(replay_tgba_run): Use it.
couvreur99_check_result::complete_cycle,
couvreur99_check_result::accepting_path): Record conditions and
acceptance conditions in the accepting run. Simplify the
todo BFS stack for accepting_run and complete_cycle.
* src/tgbatest/ltl2tgba.cc (main): Do use replay_tgba_run
now everything works.
* src/tgbaalgos/replayrun.cc (replay_tgba_run): Be more verbose
when an outgoing transition is not found.
Cannot test them because the run returned by the emptiness checks
are currently incomplete (they lack the acceptance conditions, and
sometimes even the labels in the prefix).
* src/tgbaalgos/Makefile.am (tgbaalgos_HEADERS,
libtgbaalgos_la_SOURCES): Add them.
* src/tgbatest/ltl2tgba.cc (main): Prepare to use replay_tgba_run
when the emptiness checks are fixed.

break third-party code that were using these algorithms.

counter_example -> couvreur99_check_result

path, and does not run until the end of the STL container.
Remove it.
* src/tgbaalgos/tarjan_on_fly.cc, src/tgbaalgos/tarjan_on_fly.hh
(tarjan_on_fly): Do not inherit from the emptiness_search class,
because the check method will no longer return a counter example.
(tarjan_on_fly::check): Return only a boolean.
(tarjan_on_fly::build_counter): Delete.
* src/tgbatest/ltl2tgba.cc: Adjust.
