This improves the determinism in a few cases.

passes into lambdas so that they are very easy to swap.

sizes.
* spot/twaalgos/translate.cc, spot/twaalgos/translate.hh: Use
ltl-split even for BA/TGBA, but only of conjunctions with GF(..)
in those cases.

formulas.
* tests/core/parity2.test: Add another formula to the tests.
Related to issue #351.
* spot/twaalgos/sccfilter.cc: When handling weak automata, we know
they are very-weak if the SCC count is equal to the number of states.
* tests/core/dca2.test, tests/core/monitor.test,
tests/core/parity2.test, tests/core/randomize.test,

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,

bin/ltl2tgba.cc, bin/dstar2tgba.cc: Add support for --colored-parity.
* bin/ltldo.cc: Adjust as well for consistency, even if --parity and
--colored-parity is not used here.
