Printing the OpenPGP and X.509 keys used for a specific card key can

This allows to first create keys on the card (e.g. using gpg-card)
even without having any public key for OpenPGP. Then the key
generation option 14 (cardkey) can be used to create a primary OpenPGP
key from the key on the card.
There are still a couple of problems related to the agent which
creates the stub key and may run into problems if creating a second
key from the card. This will be fixed in a future patch.

This does now allows to create a single OpenPGP key optioanlly with a

gpg-card generate --algo=ed25519 OPENPGP.3
Using option --force will overwrite and already existing key.
scdaemon does here take care of swicthing the key attributes before
generating the key.
TODO: We need to add some more stuff to app-openpgp so that the user
is not annoyed by beeing asked to enter the Admin-PIN twice (change
the key attributes clear the verification state). gpg's key
generation also needs some tweaks for using an existing card key which
has no key stub in private-keys-v1.d.

* g10/verify.c (verify_files): Track the first error code.
--
It seems to be possible to play tricks with packet structures so that
log_error is not used for a bad input data. By actually checking the
return code and let the main driver in gpg call log_error, we can fix
this case.
Note that using gpg --verify-files and relying solely on gpg's return
code is at best a questionable strategy. It is for example impossible
to tell which data has been signed.

This change shows the key attributes of an OpenPGP card instead of the

because for uniformity it is better to do this directly in

This function is intended as a more general version of gpg's

uses static table of algorithm strings instead. There should be only

we do internally in gpg's pubkey_string and the static buffers all

Note that some of the changes are required because we can't rely that

Testing the PIN cache can currently only be done my modifying the
code to do a verification for each operation. Only some basic testing
has been done. Clearing the PIN cache is also not fully
implemented. With the forthcoming changes to app-piv we should be
enter able to test the PIN cache.

- The agent should be able to selectively clear the cache on a per

- We should replace AESWRAP by OCB.

This change does away with encrypting and decrypting the cached PIN in
