ltlmix.
* tests/core/ltlmix.test: New file.
* tests/Makefile.am: Add it.
* spot/tl/randomltl.hh (has_unary_ops): New method.
* spot/tl/randomltl.cc: Avoid creating subformulas of even size
when we do not have unary operators.
* tests/core/randpsl.test: Test it.
* NEWS: Mention it.
The error message, inherited from ltl2tgba, used to say "No formula to
translate", but "translate" isn't appropriate here.
* bin/common_finput.cc, bin/common_finput.hh (check_no_formula): Allow
"translate" to be changed.
* bin/ltlgrind.cc: Change it.
* tests/core/ltlgrind.test: Test it.
It is illegal to capture the element of a structured binding
in C++17, GCC 15 will complain about it.
* spot/twaalgos/synthesis.cc: Move the illegal structured binding
inside the lambda.
We should have [*0]|f ≡ f when f is a SERE that already accept the
empty word. Fixes issue #454.
* spot/tl/formula.cc: Implement the rewriting.
* tests/core/reduccmp.test: Add a test case.
* doc/tl/tl.tex, NEWS: Document it.
* spot/tl/formula.hh, spot/tl/formula.cc: Update the properties
and track them.
* tests/core/kind.test: Augment the test case.

Related to issue #587.
* spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh: Add
support for option "rde".
* bin/spot-x.cc, NEWS: Mention it.
* tests/core/deadends.test, tests/core/ltl2tgba2.test,
tests/python/atva16-fig2a.ipynb, tests/python/deadends.py: Adjust test
cases to reflect the improvement.
* tests/core/ltlsynt.test: Also adjust this test case, which is the
only one worsened. Some extra gates are generated when translating
GFa<->GFb with --algo=ds or --algo=sd. Issue #588 would be one way to
fix that.
The explicit way of splitting suffers if there are
too many input APs, two new ways of splitting
are introduced as well as a heuristic to chose
between them.
* NEWS: update
* spot/twaalgos/synthesis.cc,
spot/twaalgos/synthesis.hh: New fonctions
* bin/ltlsynt.cc: Add corresponding option
* tests/core/gamehoa.test,

tests/python/_synthesis.ipynb,
tests/python/game.py,
tests/python/split.py,

GCC 12/13/14 can emit spurious warnings for something
as innocent as vec.insert(vec.begin(), 12)...
Reported by Antoine Martin and Quentin Rataud.
* m4/gccwarn.m4: Test the above code and disable GCC's
-Wnull-dereference warning if necessary.
* debian/control: Remove the ipython3-notebook alternate
build-depends, as this package was removed from Debian in 2016. Add
gdb ad build-depends, in attempt to fix some OSB builds.
* spot/twaalgos/degen.hh (is_partially_degeneralizable): Pass the
forbid vector by reference, and document it. I hope that not passing
forbid by copy will get rid of a spurious "potential nullptr" warning
by gcc on Arch Linux.
* spot/twaalgos/degen.cc: Adjust, and refactor the code a bit.
* spot/twaalgos/toparity.cc: Likewise.
Python 3.12 introduced some subtle changes in the way doc strings are
displayed by help(). This was causing spurious errors in the
following test.
* tests/python/formulas.ipynb: Use print(x.__doc__) instead of
help(x).
We had some incorrectly escaped strings that are now causing
SyntaxWarnings with Python 3.12
* bin/options.py, python/spot/aux_.py, python/spot/ltsmin.i,
python/spot/__init__.py: Here.
* NEWS: Mention the fix.
For issue #570.
* spot/twaalgos/cleanacc.hh,
spot/twaalgos/cleanacc.cc (reduce_buchi_acceptance_set_here,
enlarge_buchi_acceptance_set_here): New functions.
* bin/autfilt.cc: Add options --reduce-acceptance-set and
--enlarge-acceptance-set.
* tests/core/basetred.test: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention it.
Commit bda40a5f introduced a subtle bug where nm_minato was being
increased in more cases causing some non-deterministic automata to be
incorrectly tagged as deterministic automata.
Fixes issue #575, reported by Dávid Smolka.
* spot/twaalgos/simulation.cc (create_edges): Do not increment
nm_minato when dest is bddfalse.
* tests/core/568.test: Add Dávid's first test-case.
* tests/python/forq_contains.py: Add Dávid's second test-case.
* bin/ltlsynt.cc: Also simplify subformulas using polarity and global
equivalence. Add support for --polarity=before-decompose and
--global-equiv=before-decompose to restablish the previous behavior.
* spot/tl/apcollect.hh,
spot/tl/apcollect.cc (realizability_simplifier::merge_mapping): New
method.
* tests/core/ltlsynt.test: Add new test cases.
The \f(CW macro to switch to "constant-width" does not seem to
honored when converting to html, and I've found some patch to
groff removing its use from their own man page.
https://lists.gnu.org/archive/html/groff-commit/2020-07/msg00015.html
Lets use \fC instead, as it seems to produce some <tt> in HTML.
Two manpages had URLs pointing to spot.lrde.epita.fr instead of
spot.lre.epita.fr.
Finally, spot-x.x had an incorrectly closed .EX block, that completly
broke the HTML conversion.
* bin/man/autcross.x, bin/man/ltl2tgba.x, bin/man/ltlcross.x,
bin/man/spot-x.x, bin/man/spot.x: Fix the aforementioned issues.
help2man used characters in the range 0x80,...,0x84 to mark special
sections/characters during its processing, but those bytes where also
occurring in other utf-8 characters breaking the output. For instance
the character '₁' ( a subscript 1), is encoded as "0xE2 0x82 0x81" in
utf-8.
* tools/help2man: Tell perl that input and output should be assumed to
be utf-8. Also use "private-use codepoints" for those special
characters to avoid any future conflict.
Since we now require Python 3.6, we can use f-strings instead of
format() to make the code more readable.

This uses the same trick as discussed in issue #566 and issue #568.
* spot/twaalgos/determinize.cc (safra_support): Use a basis
if it is smaller than 2^|support| for the current Safra state.
* tests/core/568.test: Add some tests.
* NEWS: Mention the optimization.
Closes issue #568.

Implement an alternate loop based on edge_separator::basis to iterate
over a signature to build results.
