* bin/common_hoaread.hh (hoa_processor): Add a abort_on_error
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/core/ltl2tgba2.test, tests/core/satmin.test,
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
* spot/twaalgos/split.cc, spot/twaalgos/split.hh: move the code and
implement the improvements
* tests/Makefile.am, tests/python/split.py: test it
* tests/core/ltlsynt.test: update existing tests to reflect the changes
Reported by Simon Jantsch and David Müller.
* spot/twaalgos/isunamb.cc (is_unambiguous): Rewrite wihtout assuming
that the product of two accepting SCCs is accepting, Also use
the result of is_accepting_scc()/is_rejectng_scc() when available.
* spot/twaalgos/sccinfo.cc, spot/twaalgos/sccinfo.hh: Make it
possible to check the acceptance of a unique SCC.
* tests/core/unambig.test: Add more test cases.
Reported by Simon Jantsch and David Müller.

J. Křentínský, and S. Sickert, submitted to LICS'18. We should add
proper references to the code and documentation once that paper is
accepted.

Fixes#333.
* spot/twaalgos/remfin.cc, spot/twaalgos/remfin.hh,
spot/twaalgos/totgba.cc: Adjust. The assert() added
to remove_fin() triggered a lot of failure in the test
suite before the different functions were fixed.
* tests/core/remfin.test, tests/python/tra2tba.py:
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.
