This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.

* scd/app-piv.c (do_readcert): Add hack to read Yubikey attestaions.
--
Use
gpg-card 'readcert PIV.ATST.9A >x.crt'
to store the attestation certificate for 9A into X.CRT.

* scd/app-piv.c (do_readkey): Read the key from the cert here instead
of letting the upper layer do this.
(do_writecert): Check that the cert matches the key and that a key has
already been generated.

* scd/command.c (cmd_readkey): Refactor to use that new function and
handle the --advanced flag only here.
* scd/app.c (app_readkey): Remove parm advanced.
* scd/app-common.h (struct app_ctx_s): Remove parm advanced from the
readkey member.
* scd/app-nks.c (do_readkey): Adjust for removed parm.

Note that ECDH decryption has not been tested due to the lack of ECC
support in gpgsm.

(send_keypair_and_cert_info): Print certinfo only if we got a cert..
(readcert_by_tag): Add arg r_mechanism and implement reading of public
keys.
(get_keygrip_by_tag): Use a public key to compute the keygrip.

(get_key_algorithm_by_dobj): Get the algorithm also from a public key.
(does_key_exist): String changes.
(do_genkey): Remove result caching and store public key in the DO.
--
This removes the result cache and instead stores the public key in the
certificate object. This allows to properly list public keys at any
time after generating a key and before a new certificate is stored
there.

authentication. More support will follow soon.
Tested with Yubikey-5.
