option.
* bin/autcross.cc: Use it.
* tests/core/autcross4.test: Add many more error cases to improve
coverage.
This also improve the coverage of the is_colored() function, because
it was not used in negative cases so far.
* bin/autfilt.cc: Implement it.
* tests/core/satmin2.test: Test it.
* NEWS: Mention it.
* bin/autfilt.cc: Fix the --help string for --complement, and also
merge edges in the resulting automaton, as suggested by František
Blahoudek.
* tests/core/complement.test: Adjust output and add František's
example.
* spot/twaalgos/gfguarantee.cc: Combine the last letter read
with the first one of the next pass when doing transition-based
acceptance. Also move the initial states to the source of any
accepting transition if the input is deterministic.

tests/python/stutter-inv.ipynb: Reduce expected sizes of a few
automata.
Improve the way transitions are duplicated when preparing the turn-based
game for synthesis. The resulting arena should now be deterministic on
nodes owned by the environment. Also move the code to another file, so
that it is easier to test (e.g. in Python).
* bin/ltlsynt.cc: move the code

Adjust expected result.
* NEWS: Mention the bug.
spot::acc_cond::mark_t is implemented as a bit vector using a single
unsigned, and implicit conversions between mark_t and unsigned may be
confusing. We try to use the proper interface.

property.
