* src/tgba/tgbagraph.hh, src/tgba/tgbagraph.cc: Add a copy constructor,
and some method to purge unreachable states.
* src/graph/graph.hh (defrag_states): Erase transition of removed
states.
* src/tgbaalgos/complete.cc, src/tgbaalgos/compsusp.cc,
src/tgbaalgos/dtgbacomp.cc, src/tgbaalgos/simulation.cc,
src/tgbatest/checkpsl.cc, src/tgbatest/emptchk.cc,
src/tgbatest/ltl2tgba.cc: Adjust to use make_tgba_digraph() instead
of tgba_dupexp_dfs() or tgba_dupexp_bfs().
* src/tgbaalgos/dupexp.cc, src/tgbaalgos/dupexp.hh: Use
make_tgba_digraph() when possible.
* src/tgbatest/det.test, src/tgbatest/sim.test: Adjust expected results.
They are not used in Spot, and their interface is really horrible. They
are used in SOG-ITS to implement the SLAP product from TACAS'11, so we
should support the functionality eventually, but maybe using the new
kind of properties that can be attached to automata. In the meantime,
these classes are making refactoring harder.
* src/tgba/futurecondcol.cc, src/tgba/futurecondcol.hh,
src/tgba/tgbascc.cc, src/tgba/tgbascc.hh: Delete.
* src/tgba/Makefile.am, src/tgbatest/ltl2tgba.cc,
src/tgbatest/checkpsl.cc, src/tgbatest/emptchk.cc: Adjust.
So that running valgrind is a lot more efficient. Running
ltl2tgba.test using to take more than 15min. We are now down to
25sec.
* src/tgbatest/checkpsl.cc: New file.
* src/tgbatest/Makefile.am: Add it.
* src/tgbatest/ltl2tgba.test: Adjust.
