7a65bdf6bc specialized translation for GF(guarantee) and FG(safety)
This is adapted from a proposition in a paper by J. Esparza,
J. Křentínský, and S. Sickert, submitted to LICS'18.  We should add
proper references to the code and documentation once that paper is
accepted.

* spot/twaalgos/gfguarantee.cc, spot/twaalgos/gfguarantee.hh:
New files.
* spot/twaalgos/Makefile.am, python/spot/impl.i: Add them.
* spot/twa/fwd.hh: Add a forward declaration of bdd_dict_ptr.
* spot/twaalgos/postproc.cc, spot/twaalgos/postproc.hh: Make it
possible to call finalize() from the translator subclass.  Constify
all the do_* functions while we are there.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Add
a "gf-guarantee" option to decide whether to use the new translation.
* bin/spot-x.cc: Document it.
* tests/core/dca2.test, tests/core/genltl.test,
tests/core/ltl2tgba2.test, tests/core/parity2.test,
tests/core/satmin.test, tests/python/automata.ipynb,
tests/python/sbacc.py: Adjust test cases.
* tests/python/except.py: Add a couple more tests.

689aa7fdc0 translate: add support for -x tls-impl=N
This is long overdue, and we probably want to use tls-impl=1 in
ltlsynt.

* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh:
Add support for tls-impl=N.
* tests/core/ltl2tgba.test: Test it.
* bin/spot-x.cc, NEWS: Document it.

05abed6d2f translate: use relabel_bse() to speed translations with a lot of APs
Fixes #268, reported by Yann Thierry-Mieg.

* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Call
relabel_bse() + relabel_here().
* tests/core/format.test: Add a test case.
* bin/spot-x.cc, NEWS: Document the change.

f07fbbae79 ltl2tgba: clear simplification cache between translations
The cache used in formula simplification will keep atomic propositions
defined between several translations, and may impact variable order.
Reported by Maximilien Colange.

* spot/tl/simplify.hh, spot/tl/simplify.cc,
spot/twaalgos/translate.cc, spot/twaalgos/translate.hh (clear_cache):
New method.
* bin/ltl2tgba.cc, bin/ltl2tgta.cc: Call it.
* spot/twaalgos/stats.cc: Do not keep a point to the formula after
printing statistics.
* tests/core/ltl2tgba.test: Add a test case.
* tests/core/readsave.test: Adjust one formula.
* NEWS: Mention the issue.

ce63c30c0b translate: reset the LTL simplifier on set_level().
Fix an issue reported by Tomáš Babiak, who noticed that he could not
manage to have ltl2tgba process `genltl --go-theta=N` efficiently for
larger values of N.

* spot/twaalgos/translate.hh (set_level): Reset any owned LTL simplifier
whenever the optimization level is changed.
* NEWS: Mention the bug.
