simplify: GF(f)=GF(dnf(f)) FG(f)=FG(cnf(f))
These rules come from Delag's paper, and help some cases in issue #385. * spot/tl/simplify.cc: Implement the simplification. * doc/tl/tl.tex, NEWS: Document it. * tests/core/385.test: New file. * tests/Makefile.am: Add it. * tests/core/reduccmp.test: More tests. * tests/core/ltl2tgba2.test: Adjust one improved case. * tests/python/automata.ipynb, tests/python/twagraph-internals.ipynb: Adjust expected output, as the cnf/dnf reorder some subformulas.
