We have some cross-realm principals in an MIT KDB with one kind of
1DES enctype, but the other realm's KDCs issue x-realm TGTs where
the ticket encpart key enctype is a different 1DES enctype. We need
this to work if we use Heimdal with the MIT HDB backend.
An alternative would be to check for similar (or, rather,
compatible) enctypes in the KDC (and elsewhere?). This patch avoids
the need to make such ugly changes elsewhere.
Also: add support for ignoring null enctype / zero-length keys,
which *can* be found in MIT DB entries created in pre-historic
times.
Also: make the mitdb HDB backend more elegant (e.g., use the ASN.1
compiler's generated sequence/array utility functions.
Also: add a utility function needed for kadm5 kvno change
improvements and make kadmin's mod --kvno work correctly and
naturally.

Fixed a double-free bug that was triggered by MIT KDB entries with
multiple kvnos in non-increasing order.
Added lots of comments regarding the MIT KDB entry format.
