    Adds a reference from a cnode its cptr · 83e8ef65

            Rationale: When the `revoke` handler is called for a particular
            cspace, cnode, and object, the cptr associated with that cnode
            needs to be free'd so it can be re-used by other objects (given
            there are a relatively small number of cptrs in a cspace).
            We can discover the cptr_cache associated with a cspace by
            looking at the `cspace->owner` field (which we point at our
            cache), but we can't figure out from the cnode alone which
            pointer in that cache points to the given cnode. This
            information is known when the cnode is created, so I added a
            field to the cnode that contains this information.
