fix inverted Ord for TrustLevel (intermediate commit)

This commit removes the Ord and Enum instances, commenting out all code
that depends on them, to make sure that all code effected by the
inversion fix has been identified.

(Assuming no ifdefs involve TrustLevel.)

The next commit will fix up all the identified code.
