RFC 4370 requires the criticality flag to be present and set to TRUE.  I also
note that slapd by default tolerates this behavior, and provides the disallow
proxy_authz_non_critical directive to behave in strict accordance with RFC
4370.

I've introduced a corresponding proxy-authz-[non-]critical flag in idassert.
