broaden AuthDigestMiddleware.authorization_required

The interface of this internal function has changed in a backwards
incompatible way. The last parameter is no longer the bool stale, but an
exception now, which encodes more information than the previous bool.
This was made possible by the previous commit. This exception can then
be used by the new method www_authenticate to generate a suitable
WWW-Authenticate header. The idea behind this change is that at some
point it should be possible to override authorization_required (still
internal now) to evaluate what condition lead to the failure and to
generate custom error pages.
