Bug introduced in abe2c08b, visible in tests/python/product.ipynb,
and tests/python/acc_cond.ipynb.
* spot/twa/acc.hh: fix operator| and operator&.
* tests/python/acc_cond.ipynb: Adjust test case.
Operator &= used to always move Fin to the front, it does not anymore.
The only thing it does now is to merge Inf(x)&Inf(y) as Inf({x,y}).
Operator |= is now symmetrical and merges Fin()s.
Fixes#253.
* spot/twa/acc.cc, spot/twa/acc.hh: Simplify &= and make |= symmetrical.

These two functions were doing almost identical work, the only
difference was the way to select the SCC to keep. Now we have a more
uniform way to do that. Closes#172.
* bin/autfilt.cc: Offer a unique --decompose-scc option, but keep
--decompose-strength as an alias for backward compatibility.
* spot/twaalgos/strength.cc, spot/twaalgos/strength.hh: Rename
decompose_strength as decompose_scc, and handle a way to list
all SCC numers in the string specifier. This gets rid
of the nearly identical
* tests/core/scc.test, tests/core/strength.test,
tests/python/decompose.ipynb, tests/python/decompose_scc.py: Adjust
test cases.
* NEWS: Adjust.
Fixes#271, reported by Henrich Lauko.

of disjunction of Fin.
* tests/core/scc.test, tests/python/accparse2.py: Add more
tests.

value is a Boolean formula.

modification.

the modification.
Simplify some automata where some marks are identical,
or complementary to another. Fixes #216.
* NEWS: mention the new function.
* spot/twaalgos/cleanacc.cc, spot/twaalgos/cleanacc.hh: Implement
the function.
* tests/Makefile.am, tests/python/merge.py: Test this implementation.
Fixes#262 again. Reported by Maximilien Colange.
* spot/twaalgos/simulation.cc: Use state numbers to order classes, not
their signatures. The problem was that even if two simulation of the
same automaton assign the same signature, the BDD identifier used for
that signature might be different, and therefore the ordering obtained
by using BDDs as keys in a map can be different. A side-effect of
this change is that the order of states in automata produced by
simulation-based reduction may change; many tests had to be updated.
* tests/core/ltl2tgba.test: Add a new test case based on Maximilien's
report.
