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.

no rejecting cycle, reduce its acceptance to t instead of Büchi.

true acceptances.
* NEWS: Mention these two changes.
* spot/twaalgos/sccfilter.hh: Update documentation.
* spot/twaalgos/determinize.cc (tgba_determinize): The call
to scc_filter assume that the input BA is never reduced to t
acceptance. Call scc_filter with an extra option to ensure that.
* spot/twaalgos/postproc.cc (do_scc_filter): Adjust to add the
extra option when we want to build Büchi or coBuchi.
(ensure_ba): Don't mark trivial SCCs as accepting.

Part of issue #546 reported by Rüdiger Ehlers
* spot/twaalgos/product.cc (product_susp): Fix detection and handling
of unsatisfiable/universal acceptances.
* tests/python/_product_susp.ipynb: Add test cases.
This improves the determinism in a few cases.
* spot/twa/twagraph.cc (merge_edges): Encapsulate the two
passes into lambdas so that they are very easy to swap.
* spot/twa/twagraph.hh (merge_edges): Adjust documentation.
* tests/python/mergedge.py: Add test case.
* tests/core/alternating.test, tests/python/alternation.ipynb:
Determinism was improved.

tests/python/atva16-fig2a.ipynb, tests/python/decompose.ipynb,
tests/python/highlighting.ipynb, tests/python/satmin.ipynb,
tests/python/simstate.py: Adjust expected order of edges.
* NEWS: Mention the change.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Build
automata with generic acceptance by doing product of automata for
smaller subformulas.
* bin/spot-x.cc: Mention ltl-split.

code.
* spot/twaalgos/product.cc, spot/twaalgos/product.hh: Implement it.
* tests/python/_product_susp.ipynb: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention it.
