automaton.

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.

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.
* spot/twa/acc.cc (maybe_accepting): Fix handling in case
of disjunction of Fin.

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.

the function.
