[cap-talk] Delegation Bounds - correction

[Valerio Bellizzomi]

If it is possible to do this with a counter inside a capability, it would
become 'delegate N times'.
And every time the capability is passed (delegated) we do:

	if (counter < N) {
	    counter := counter + 1;
	    <allow_cap_delegation>
	}
	else {
	    <do_not_allow_cap_delegation>
	}

the upper bound N controls dept of capability delegation, and can be
re-established for every service implementation.
