an unstatisfiable mark, and fix the eval() function for
Fin acceptance.

an unsatisfiable mark. Do not assume generalized Büchi.

This implement several new options for --dot in order to
allow emptiness sets to be output as colored ⓿ or ❶...
Also add a SPOT_DOTDEFAULT environment variable.
* NEWS, src/bin/man/spot-x.x, src/bin/common_aoutput.cc,
src/bin/dstar2tgba.cc: Document the new options.

* src/tgba/acc.cc, src/tgba/acc.hh (to_text, to_html): New method.
* src/tgbaalgos/dotty.cc: Implement the new options.
* src/tgbatest/readsave.test, wrap/python/tests/automata.ipynb: More
tests.
* wrap/python/spot.py: Make sure the default argument for
dotty_reachable is None, so that SPOT_DOTDEFAULT is honored.

* src/bin/autfilt.cc: Add a --cnf-acceptance option.
* src/tgbatest/acc2.test: Test it.
Because scc_info does not perform a full emptiness check, it is not
always able to tell whether an SCC is accepting if the acceptance
condition use Fin primitives. This introduce is_rejecting_scc() in
addition to to is_accepting_scc(). Only one of them may be true, but
they can both be false if scc_info has no idea whether the SCC is
accepting.
* src/tgbaalgos/sccinfo.cc, src/tgbaalgos/sccinfo.hh: Implement
is_rejecting_scc().
* src/bin/ltlcross.cc, src/tgba/acc.cc, src/tgba/acc.hh,

src/tgbaalgos/remfin.cc, src/tgbaalgos/safety.cc,
src/tgbaalgos/sccfilter.cc: Use it.
* src/tgbaalgos/dotty.cc: Use is_rejecting_scc() and is_accepting_scc()
to color SCCs.
* doc/org/oaut.org: Document the colors used.
* src/tgbatest/neverclaimread.test, src/tgbatest/readsave.test: Adjust
tests.
* src/tgbatest/sccdot.test: New test case.
* src/tgbatest/Makefile.am: Add it.
* src/tgba/acc.cc, src/tgba/acc.hh: Move the strip() routine from
acc_cond into acc_cond::mark_t, and the strip() routine from
cleanacc.cc into acc_cond::acc_code. Introduce helper functions
to create inf()/fin()/t()/f() at the acc_code level.
* src/tgbaalgos/cleanacc.cc: Simplify, using the strip() function
from acc_code.
* src/tgbaalgos/mask.cc (mask_acc_sets): Use the strip() function
from acc_code so that it work on non-Buchi acceptance.
* src/tgbatest/maskacc.test: Add a test for the latter change.
* src/tgbaalgos/sccfilter.cc, src/tgbatest/acc.cc: Adjust the
use mark_t::strip().
* src/bin/ltlcross.cc: Remove Fin-acceptance before
doing checks. More --verbose output.
* src/tgba/acc.cc, src/tgba/acc.hh: Add an eval_sets() function
to find the set of acceptance sets needed to satisfy the condition
in an accepting SCC.
* src/tgbaalgos/gtec/ce.cc: Use eval_sets() when computing
a counter example.
* src/tgbaalgos/gtec/gtec.cc: Raise an exception when called
on an acceptance that contains Fin.
* src/tgbatest/ltl2dstar3.test, src/tgbatest/ltlcrossce2.test:
New files.
* src/tgbatest/Makefile.am: Add them.

* src/tgbaalgos/Makefile.am: Add them.
* src/tgba/acc.hh, src/tgba/tgba.hh (get_acceptance): Return a
reference.
* src/bin/autfilt.cc: Add a --cleanup-acceptance option.
* src/tgbatest/hoaparse.test: Test it.
and make sure are_isomorphic does not look only at the number of
acceptance sets
* src/tgba/acc.hh: Here.
* src/tgbaalgos/are_isomorphic.cc: Use it to ensure two automata
have the same acceptance condition.
* src/tgbatest/explpro4.test: Test product between Büchi and co-Büchi,
and make sure the isomorphic check look at the acceptance condition.
Fixes#55.
* src/tgba/acc.hh: Do not store a bdd_dict_ptr, it is not used.

src/tgba/tgbagraph.hh, src/tgbaalgos/dtgbasat.cc,
src/tgbatest/acc.cc: Adjust.
This is a huge patch, that took over a month to complete. The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.
* NEWS: Update.
* src/tgba/acc.hh: New file.
* src/tgbatest/acc.cc, src/tgbatest/acc.test: Test it.
* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete. The KV
complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets. The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.
