This is not optimal yet because it still construct a minimal WDBA
internally, but it's better than the previous way to call
minimize_obligation() since it can avoid constructing the minimized
automaton in a few more cases.

is_obligation().

Fixes#297. Implement the following rules.
Fin(i) & Fin(j) by f if i and j are complementary
Fin(i) & Inf(i) by f
Inf(i) | Inf(j) by t if i and j are complementary
Fin(i) | Inf(i) by t.

Suggested by Tobias Meggendorfer. Fixes#295.

For now, ltlsynt only handles LTL realizability. It uses a reduction to
parity game followed by Calude et al.'s reduction from parity game to
reachability game.
