Use the new C3 MRO algorithm, implemented by Samuele Pedroni (SF patch
619475; also closing SF bug 618704).  I tweaked his code a bit for
style.

This raises TypeError for MRO order disagreements, which is an
improvement (previously these went undetected) but also a degradation:
what if the order disagreement doesn't affect any method lookups?
I don't think I care.
