    Rearchitect quota checking to partially fix bug 938317.

    This is a rearchitecting/rewriting of quota handling to correct the
    quota atomicity issues highlighted by bug 938317. Partially implements
    blueprint quota-refactor as well.

    This change is fairly substantial. To make it easier to review, it has been
    broken up into 3 parts. This is the first part.
