This new quick command is in particular useful to update existing keys
so that they can be used with OCB mode.
(cherry picked from commit d40d23b233f0b2e6fc25937f1632ac5b9d4f61e5)

* dirmngr/crlcache.c (finish_sig_check): Use raw value for the data.
--
This had the usual signed/unsigned problem. By using the modern form
we enforce Libgcrypt internal parsing as unsigned integer.

This curve is a bit odd in that it does not match a common hash digest
length. We fix that here for just this case instead of writing more
general code to support all allowed cases (i.e. hash shorter than Q).

--
It might be useful to distribute revocations of old keys along with
new keys. This is in particicualrr useful for WKD stored keys. This
patch allows to put unrelated standalone revocations into a key. For
example they can simply appended to a keyblock. Right now it is a bit
inaesthetic to see diagnostics about misplaced or bad revocation
signatures.

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.

Actually the certificate has no encryption usage but we should also

This allows me to create qualified signatures using my Telesec card.
There is of course more work to do but this is the first step.
Note: The design of the FID cache needs to be reconsidered. Until
that the lookup here has been disabled. The do_sign code should be
revamped to be similar to what we do in app-p15.
