This is the first CL of several that will eventually replace TokenService with
ProfileOAuth2TokenService.  In this CL, the dependencies between TS and PO2TS
are reversed, and uneeded features are removed from TS.  This will allow
individual users of TS to be moved over to PO2TS in separate CLs, to easy
reviews.
