Constrained delegation without PAC support
Merge Luke's users/lhoward/s4u2proxy branch to trunk. Implements a
Heimdal-compatible mechanism for allowing constrained delegation
without back-end support for PACs. Back-end support exists in LDAP
only (via a new krbAllowedToDelegateTo attribute), not DB2.
