* spot/twa/acc.hh (acc_cond::mark_t): Diagnose mark_t with set numbers
that are too larges.
* tests/python/except.py: Adjust.
* tests/core/acc.cc: Remove most of asserts, as those can be disabled,
and adjust expected exception.
This corrects a bug that has never been observed yet, has it would
require more than UINT_MAX formulas allocations.
* spot/tl/formula.cc, spot/tl/formula.hh: Bump the formula ID in the
unlikely case a new atomic proposition would receive the same id as a
previous one.
* spot/twaalgos/determinize.cc: Implement various micro
optimizations. Use robin-hood hashing in a few places.
* spot/priv/robin_hood.hh: New file.
* spot/priv/Makefile.am: Add it.
* tests/sanity/80columns.test, tests/sanity/includes.test,
tests/sanity/style.test: Adjust to skip robin_hood.hh.
* spot/twa/acc.hh: Introduce parity_min_odd(n) and friends.
* spot/twaalgos/determinize.cc, spot/twaalgos/rabin2parity.cc,
spot/twaalgos/toparity.cc: Use them.
* tests/python/parity.py: Call each function exhaustively.
* NEWS: Mention the new functions.
* spot/twaalgos/aiger.cc: Simplify some bit operatitions. Force the
ordering of operations in aig_and, that was causing a test case to
fail on ARM, and greatly simplify the code and data structures used in
remove_unused().
* tests/core/ltlsynt.test: Adjust expected output.
This was prompted by reports by Andrew Wells and Yong Li.
* NEWS, doc/tl/tl.tex: Document the changes.
* THANKS: Add Andrew.
* bin/ltlfilt.cc: Match --ltl before --from-ltlf if needed.
* spot/parsetl/parsedecl.hh, spot/parsetl/parsetl.yy,
spot/parsetl/scantl.ll: Parse X[!].
* spot/tl/formula.cc, spot/tl/formula.hh: Declare the new operator.
* spot/tl/ltlf.cc: Adjust to handle op::X and op::strong_X correctly.
* spot/tl/dot.cc, spot/tl/mark.cc, spot/tl/mutation.cc,
spot/tl/print.cc, spot/tl/simplify.cc, spot/tl/snf.cc,
spot/tl/unabbrev.cc, spot/twa/formula2bdd.cc,

tests/core/ltlgrind.test, tests/core/rand.test,
tests/core/sugar.test, tests/python/randltl.ipynb: Adjust.
* tests/core/ltlfilt.test, tests/core/sugar.test,
tests/core/utf8.test: More tests.
Bison 3.0 was released in 2013, and the current Debian stable (buster)
has version 3.3.2.
* m4/bison.m4: Remove -Wno-precedence and -Wno-empty-rule, keep
-Wno-deprecated just to protect from future deprecation warnings that
would be interpreted as errors.
* spot/parseaut/parseaut.yy, spot/parsetl/parsetl.yy: Use %empty
rules, prefer %precedence over %nonassoc, update %error-versbose and
%name-prefix to their more modern equivalent.
* spot/misc/trival.hh (maybe): Mark this function as noexcept to
please the compiler while compiling the parsers.
std::cerr will flush after each operator<< by default, so it's simpler
to use \n instead of std::endl, especially if we can merge \n into the
previous string. Ideally we should prefer \n for std::cout as well,
but there are reasonable cases where we want to call std::endl there,
so it's hard to enforce.
* tests/sanity/style.test: Diagnose occurrences of cerr.*<<.*endl.
* bin/autcross.cc, bin/autfilt.cc, bin/ltlcross.cc, bin/ltlsynt.cc,
spot/tl/formula.cc, spot/twa/bdddict.cc, tests/core/checkpsl.cc,
tests/core/checkta.cc, tests/core/consterm.cc, tests/core/emptchk.cc,

tests/core/randtgba.cc, tests/core/reduc.cc, tests/core/syntimpl.cc,
tests/ltsmin/modelcheck.cc: Fix them.
Reported by Salomon Sickert.
* spot/twaalgos/complement.cc: Make sure the output of postproc
is deterministic.
* tests/core/ltlcross.test: Add test case.
* NEWS: Mention the bug.
* spot/twaalgos/product.cc: The res pointer should be
passed by reference since we reset it to nullptr when
output_aborter says "too large".
* python/spot/impl.i: Add binding for powerset.hh,
so we can use output_aborter in Python.
* tests/python/prodexpt.py: Test it.
* spot/twaalgos/genem.hh, spot/twaalgos/genem.cc
(generic_emptiness_check_for_scc): Add a version that takes an acc.
* spot/twaalgos/isweakscc.cc (scc_has_rejecting_cycle): Use
generic_emptiness_check_for_scc.
The previous patch triggered this issue again, failing
core/ltl2tgba2.test.
* spot/twaalgos/gfguarantee.cc: Separate the replaying of history from
the modification of the automaton.
* NEWS: Mention the bug.
* tests/python/twagraph-internals.ipynb, tests/python/automata.ipynb:
Adjust.
These rules come from Delag's paper, and help some cases
in issue #385.
* spot/tl/simplify.cc: Implement the simplification.
* doc/tl/tl.tex, NEWS: Document it.
* tests/core/385.test: New file.

* tests/core/ltl2tgba2.test: Adjust one improved case.
* tests/python/automata.ipynb, tests/python/twagraph-internals.ipynb:
Adjust expected output, as the cnf/dnf reorder some subformulas.
* spot/twaalgos/alternation.cc, spot/twaalgos/alternation.hh,
spot/twaalgos/complement.cc, spot/twaalgos/complement.hh,

spot/twaalgos/powerset.cc, spot/twaalgos/powerset.hh,
spot/twaalgos/product.cc, spot/twaalgos/product.hh: Use an
output_aborter argument to abort if the output is too large.
* bin/ltlcross.cc: Use complement() with an output_aborter
so that ltlcross will not attempt to build complement larger
than 500 states or 5000 edges. Add --determinize-max-states
and --determinize-max-edges options.
* tests/core/ltlcross3.test, tests/core/ltlcrossce2.test,
tests/core/sccsimpl.test, tests/core/wdba2.test,
tests/python/stutter-inv.ipynb: Adjust test cases.
* NEWS: Document this.
* bin/spot-x.cc: Add documentation for postprocessor's
det-max-states and det-max-edges arguments.
* doc/org/ltlcross.org: Update description.

* tests/Makefile.am: Add python/stutter.py.
The first issue was reported by Victor Khomenko.

version of sugar_delay().
