* 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.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.

Pierre Ganty wrote that he could not compile Spot with Swig 4.2.1
anymore, and when I upgraded from 4.2.0 to 4.2.1 I could not either.
It seems that declaring operator<< as friends in subclasses is
confusing Swig 4.2.1. See https://github.com/swig/swig/issues/2845
* spot/twa/acc.cc, spot/twa/acc.hh: Declare operator<< for
acc_cond::mark_t and acc_cond::acc_code outside the class, so that we
do not need friend declarations.

spot/twaalgos/split.hh (edge_separator::add_to_basis): Add a variant
that is limited in the number of labels it adds.

a cache of separated edges, as in the split.
This generalizes (and replaces) the two-argument split that was
introduced in c2832cabfc.
* spot/twaalgos/split.cc, spot/twaalgos/split.hh (edge_separator): New
class.

* tests/Makefile.am, doc/org/tut.org: Add it.
* NEWS: Mention it.
* spot/twaalgos/split.cc: The two split_edges() versions only differ

cleanup_acceptance_here.
* spot/twaalgos/dualize.hh: Improve documentation.
* NEWS: Mention the possible backward incompatible change.

Several people have asked for a way to check whether a word is
accepted by an automaton, including at least Jonah Romero and Scott
Buckley. So it's time we have it.
* spot/twa/twa.hh, spot/twa/twa.cc,
spot/twaalgos/word.hh (intersects): Add the new variant.

Work around a recent decision in Jupyter Lab and Notebook to render
<svg> is inline <img>, breaking tooltips or text selection.
(Rerendering all notebooks was painful.)
* NEWS: Mention the change.
* python/spot/__init__.py: Add a _repr_html_ method to all
classes that had a _repr_svg_. It seems Jupyter will use
_repr_html_ by default.
* python/spot/jupyter.py: SVG replace the _repr_svg_ method
by a _repr_html.

Most of those errors were pointed out by the language-check tool.
However while fixing those I found a few other issues that I fixed.
In particular I updated the bibliographic reference for ltlsynt,
added some DOI links for some cited papers that had no link, and
fixed the broken introduction of ltlgrind.

typos in --help text that appeared in the above org files.
Fixes#560.
* spot/parseaut/parseaut.yy: Add more comments about handling
of prop_universal in present of multiple initial states. It took
me time to figure out that it was done correctly. Also only
reset prop_complete() in the case an initial state is reused.

* tests/python/parsetgba.py: Add tests for complete.
* doc/org/hoa.org: Add more text about the effect of fusing initial
states.

"universal". The former was obsoleted in Spot 2.4.
Several test cases started failing after updating to Swig 4.2 because
the spot.ltsmin module and the spot.impl module were using different
names for atomic_prop_set. This seems to work around it.
* python/spot/impl.i: Specify the full type for atomic_prop_set.
Apparently using `#if defined(X) or defined(Y)` did not
trouve the compilers, but Swig was confused by the "or".

* spot/twaalgos/postproc.hh (postprocess::acd_): Default to true.

to color an automaton, do not run scc_filter to remove color
from transiant edges.
* tests/python/acd.py: New file.
* tests/Makefile.am: Add it.
Fixes#557.
* spot/tl/apcollect.cc (realizability_simplifier): When detecting
global equivalence such as o1 := i2, the left is always an output, so
it should never be marked as input.
* tests/core/ltlsynt.test: Add test case.
* spot/twaalgos/alternation.hh, spot/twaalgos/alternation.cc: Add the
