* spot/twaalgos/hoa.cc: Use "aliases" while encoding BDDs for
output.
* spot/twaalgos/hoa.hh: Add helper function to set/get aliases.
* python/spot/impl.i: Create a type for aliases.

https://gitlab.com/graphviz/graphviz/-/issues/2179
* spot/twaalgos/dot.cc: Avoid initial newline in title.
* NEWS: Mention the bug.
* tests/core/det.test, tests/core/dstar.test,
tests/core/neverclaimread.test, tests/python/automata-io.ipynb: Adjust
test cases.
Reported by Reuben Rowe.
* spot/twaalgos/complement.cc (complement): Remove the hard-coded
simul=0 option on automata with >32 states. In 2.10 simul=0 now
implies det-simul=0, causing the regression, and most importantly it
is not needed anymore, because we have other threashold like simul-max
and simul-trans-pruning in place.
* tests/core/complement.test: Add Reuben's automaton as test case.
* NEWS: Mention the fix.
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.
* spot/parsetl/scantl.ll: Diagnose delays (##n) larger than
unbounded(). Remove all checks for delays with 1 or 2 characters.
* tests/core/parseerr.test: Add a test case.
* NEWS: Mention this fix.
* spot/kripke/kripkegraph.hh, spot/misc/hash.hh, spot/twa/taatgba.cc,
spot/twa/twagraph.hh, tests/core/ngraph.cc: Replace subtraction of
pointeur minus nullptr by an explicit cast to size_t.
* spot/twa/acc.hh: Add explicit default copy assignment operator for
rs_pair.
For issue #485.
* spot/tl/formula.cc, spot/tl/formula.hh: Catch min/max overflow
when the operators are constructed. Also disable travial
simplification rules that would create such overflow.
For instance x[*200][*2] will not become x[*400] anymore.
* python/spot/impl.i: Catch std::overflow_error.
* tests/core/equals.test, tests/python/except.py: Add test cases.
Fixes#480.

those lists using regexes. Add entries for Owl 21.0.
(show_shorthands, tool_spec): Adjust to use those regexes.
* doc/org/autcross.org, doc/org/ltlcross.org, doc/org/ltldo.org:
Update the list of shorthands.

spot/twaalgos/synthesis.hh (synthesis_info): ... here, because this
structure contains only synthesis stuff. Also rename "solver" to
"algo" to match the ltlsynt option.
(solve_game): Move the two argument version of this function here,
since that's the only game-related generic function that use
synthesis_info.
* bin/ltlsynt.cc, tests/core/ltlsynt.test, tests/python/games.ipynb,
tests/python/synthesis.py, NEWS: Adjust all uses and mentions.
* bin/ltlsynt.cc: Implement the new option, and make it default
to bisimulation with output assignment (a.k.a. bwoa).
* NEWS, bin/spot-x.cc, doc/org/ltlsynt.org: Update the documentation.
* spot/twaalgos/game.hh: Make bwoa the default.

* tests/core/ltlsynt.test: Adjust tests
* tests/python/split.py: Adjust tests
Introduce a new, uniform way to create and solve
games.
Games can now be created directly from specification
using creat_game, uniformly solved using
solve_game and transformed into a strategy
using create_strategy.
Strategy are mealy machines, which can be minimized.

for named properties

The merging is (possibly) more expensive but also
merges more states when applied to all states.
* spot/graph/graph.hh: edge sorting
* spot/twa/twagraph.cc,
spot/twa/twagraph.hh: selective state merging
* tests/core/twagraph.cc: Adjusting tests
Aiger circuits noew have their own class.
Monitors can be translated to and obtained
from aiger circuits.
Moreover a step by step evaluation method
is provided.
* spot/twaalgos/aiger.hh,

This will be handy latter to develop widgets with interactive
highlighting of automata.
* spot/twaalgos/dot.cc: Implement it.
* bin/common_aoutput.cc, NEWS, doc/org/oaut.org,
doc/org/spot.css: Document it.
* tests/core/alternating.test, tests/core/readsave.test,
tests/core/sccdot.test: Test it.
* spot/twa/twagraph.cc (merge_states): Return the number
of removed states, and use that to decide if defrag_states
is needed.
* spot/twa/twagraph.hh, NEWS: Document that.
* tests/core/tgbagraph.test, tests/core/twagraph.cc: Adjust test case.
* spot/twa/twagraph.cc: Implement it.
* spot/twa/twagraph.hh, NEWS: Document it.
* tests/python/mergedge.py: Test it.
* tests/core/ltlsynt.test, tests/python/games.ipynb: Adjust expectations.
We have enough outputs checked verbatim everywhere so that testing
that three execution of a single command return the same output is now
a waste of time.
* tests/core/simdet.test: Remove.
* tests/Makefile.am: Adjust.
Also have simul-max default to 4096 instead of 512, because it's
really simul-trans-pruning that is very slow and need to be limited.
* spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh,
spot/twaalgos/simulation.cc, spot/twaalgos/simulation.hh,
spot/twaalgos/determinize.cc, spot/twaalgos/determinize.hh:
Implement the above options.
* bin/spot-x.cc, NEWS: Document them.
* tests/core/ltlsynt.test, tests/core/minusx.test,
tests/core/sim3.test: Add some test cases.
This fixes#452, and also fix a bug related to transiant SCCs
incorrectly merged in cosimulation: the source of the edges was
updated without fixing the chaining of the edges.
* spot/twaalgos/simulation.cc: Fix all the above.
* tests/python/simstate.py: Add test case from issue #452.
* tests/core/det.test, tests/core/ltlsynt.test,

spot/parseaut/scanaut.ll: Add support for #line.
* tests/core/parseaut.test: Test it.
* NEWS: Mention it.
Because the loops iterate in the opposite order, multiple
test cases need to be adjusted.
* spot/taalgos/tgba2ta.cc, spot/twaalgos/alternation.cc,
spot/twaalgos/dualize.cc, spot/twaalgos/ltl2tgba_fm.cc,
spot/twaalgos/simulation.cc, spot/twaalgos/stutter.cc,
spot/twaalgos/toweak.cc: Replace loops based on
bdd_satonest(x,y,bddtrue) by loops based on minterms_of(x,y).
* tests/core/degenscc.test, tests/core/dualize.test,
tests/core/genltl.test, tests/core/readsave.test,
tests/python/alternation.ipynb, tests/python/automata.ipynb,
tests/python/decompose.ipynb, tests/python/decompose_scc.py,
tests/python/dualize.py, tests/python/sccinfo.py,
tests/python/simstate.py, tests/python/testingaut.ipynb,
tests/python/word.ipynb: Adjust expected test cases. The
only regression is in genltl.test, but the worsened case
should eventually be fixed as discussed in issue #425 anyway.
This proceeds from a discussion with Michaël Cadilhac.

method.

Renkin.

When gf-guarentee works and produce a deterministic automaton, use it
right away without comparing it with the automaton produced by the
regular translation. This used to be the case for all -D scenarios
except -G -D.

gf_guarantee_to_ba_maybe() or fg_safety_to_dca_maybe() whenever -D is
used.

iron out some slight output differences.

results in the test cases.
* tests/python/automata.ipynb, tests/core/prodor.test: Adjust to new
