* spot/twaalgos/gfguarantee.cc: Combine the last letter read
with the first one of the next pass when doing transition-based
acceptance.  Also move the initial states to the source of any
accepting transition if the input is deterministic.
* tests/core/ltl2tgba2.test, tests/core/satmin.test,
tests/python/stutter-inv.ipynb: Reduce expected sizes of a few
automata.

Improve the way transitions are duplicated when preparing the turn-based
game for synthesis. The resulting arena should now be deterministic on
nodes owned by the environment. Also move the code to another file, so
that it is easier to test (e.g. in Python).

* bin/ltlsynt.cc: move the code

This is needed so that SVG files are included as an <object...> rather
than as an <img...>, which in turn is needed to ensure SVG tooltips
will work.  We do not explicitly require org-mode 9.1, but we install
it if it is not present.
