This fixes#492, based on a report from Jérôme Dubois.
* spot/twaalgos/sbacc.cc: If the initial state is in a rejecting
component, start with an initial state whose colors are unsat_mark.
* tests/core/sbacc.test: Add test case.
* tests/python/pdegen.py: Adjust it.
This improves the determinism in a few cases.
* spot/twa/twagraph.cc (merge_edges): Encapsulate the two
passes into lambdas so that they are very easy to swap.
* spot/twa/twagraph.hh (merge_edges): Adjust documentation.
* tests/python/mergedge.py: Add test case.
* tests/core/alternating.test, tests/python/alternation.ipynb:
Determinism was improved.
* tests/core/parity2.test, tests/core/readsave.test,
tests/core/sbacc.test, tests/python/_product_susp.ipynb,
tests/python/atva16-fig2a.ipynb, tests/python/decompose.ipynb,
tests/python/highlighting.ipynb, tests/python/satmin.ipynb,
tests/python/simstate.py: Adjust expected order of edges.
* NEWS: Mention the change.
* bin/common_post.cc, bin/randaut.cc: Implement -b/--buchi.
Also add --sba as alias for -B, and --gba as alias for --tgba.
* NEWS: Document those changes.
* doc/org/ltl2tgba.org, doc/org/oaut.org: Adjust documentation.
* tests/core/ltl2tgba2.test, tests/core/ltlcross2.test,
tests/core/randaut.test: Add more tests.
* tests/core/sbacc.test: --sbacc cannot be abbreviated as --sba
anymore.
Fixes#312, reported by František Blahoudek.
* spot/twaalgos/sbacc.cc: Detect the case were this can happen,
and fix it.
* tests/core/sbacc.test: New test case.
* NEWS: Mention the bug.
Our use of
ltl2tgba=ltl2tgba
autfilt=autfilt
...
all over the test cases comes from the time where those tools were not
in PATH and we actually had something like
ltl2tgba=../../bin/ltl2tgba
autfilt=../../bin/autfilt
But today that is useless, and we prefer to write ltl2tgba rather than
$ltl2tgba, so let's remove this old cruft.

Fixes#282.
