Syncing with Pynac will allow limited but fast decision making (without
Maxima) through already existing flag logic in Pynac.

The branch of this ticket contains adaptions on the Sage side. The Pynac
interface declarations are already committed (appearing in version
0.4.4+). The complete interface may be in Pynac-0.5.
