This extends the long available OCB and EAX decryption feature.  Due
to the meanwhile expired patent on OCB there is no more reason for
using EAX.  Thus we forcefully use OCB if the AEAD feature flag is set
on a key.

In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.
