Rename is_safety_automaton() as is_guarantee_automaton() and

implement is_safety_mwdba().

Note: I swapped the name of safety and guarantee when I
implemented is_safety_automaton() on 2010-03-20.  Fortunately,
is_safety_automaton() was only used where is_guarantee_automaton()
would have been correct.

* src/tgbaalgos/safety.cc (is_guarantee_automaton): Rename as ...
(is_guarantee_automaton): ... this.
(is_safety_mwdba): New function.
* src/tgbaalgos/safety.hh: Adjust and add documentation.
* src/tgbaalgos/minimize.cc: Use is_guarantee_automaton() instead
of is_safety_automaton().
* src/tgbatests/safety.test: Rename as ...
* src/tgbatests/obligation.test: ... this, and augment the
test.
* src/tgbatest/Makefile.am: Adjust.
* src/tgbatest/ltl2tgba.cc (-O): Display whether a formula
represent a safety, guarantee, or obligation property.
* NEWS: Adjust.

@ -36,9 +36,10 @@ New in spot 0.6a:
-ks: traverse the automaton to compute its number of states and
transitions (this is faster than -k which will also count
SCCs and paths).
-Rn: Minimize automata for obligation formulae.
-M: Build a deterministic monitor.
-O: Tell whether an automaton is a safety automaton.
-O: Tell whether a formula represents a safety, guarantee, or
obligation property.
-Rm: Minimize automata representing obligation properties.
* The on-line tool to translate LTL formulae into automata
has been rewritten and is now at http://spot.lip6.fr/ltl2tgba.html
It requires a javascript-enabled browser.
