This massive set of changes was triggered by issue #546. In addition to the better handling of !weak, this also adds some weak properties in a few places. * spot/twaalgos/product.cc (product_aux): Throw some exception if an automaton with t or f acceptance has the !weak property. This is a cheap sanity check to help detect algorithms that incorrectly assumed !weak input would necessarily become !weak output. * spot/twaalgos/hoa.cc (print_hoa): Likewise, also do not assume that terminal implies very-weak. * spot/parseaut/parseaut.yy: Add several diagnostics for similar cases. E.g., a one-state automaton cannot be declared as !very-weak. * tests/core/parseaut.test: Check those new diagnostics. * spot/twa/twa.cc (twa::intersecting_run): Temporary remove the weak property by setting it to maybe, not to false. * spot/twaalgos/minimize.cc, spot/twaalgos/parity.cc, spot/twaalgos/sccfilter.cc, spot/twaalgos/simulation.cc: Account for the fact that these algorithm may in fact improve the weakness. * spot/twaalgos/strength.cc: Only look at colors used by the acceptance condition when deciding weakness. * spot/twaalgos/synthesis.cc: Declare the strategy as weak. * bin/randaut.cc: Add weak to automata with t/f acceptance. * spot/kripke/kripke.hh: Make kripke structures as weak. * tests/core/acc_word.test, tests/core/alternating.test, tests/core/complement.test, tests/core/complete.test, tests/core/ltlsynt.test, tests/core/randomize.test, tests/core/readsave.test, tests/core/remfin.test, tests/core/sccsimpl.test, tests/core/strength.test, tests/core/wdba2.test, tests/ltsmin/kripke.test, tests/python/automata-io.ipynb, tests/python/automata.ipynb, tests/python/dbranch.py, tests/python/highlighting.ipynb, tests/python/kripke.py, tests/python/ltsmin-dve.ipynb, tests/python/mealy.py, tests/python/simstate.py: Adjust all these test cases. * NEWS: Mention the fixes.
