Add requestId to authentication entry points.

The CancellationSignal passed into the authentication methods is not
associated with the request and can be used to cancel the current
operation, even if it is more recent. The new id prevents outdated
signals from being using.

Note that there are still issues with the Callbacks that are not
addressed (see bug for details).
