* scd/app-nks.c (filelist): Tweak 0x4531.
--
Actually the certificate has no encryption usage but we should also
tell that via KEYINFO so that this key is never tried to create an
encryption certificate.
(cherry picked from commit 3a2fb1c306)
* scd/app-nks.c (find_fid_by_keyref): Factor keyref parsing out to ...
(parse_keyref): new.
(do_readcert): Use new function instead of partly duplicated code.
Make detection of keygrip more robust.
(do_readkey): Make detection of keygrip more robust.
(do_with_keygrip): Use get_nks_tag.

Also added a couple of comments.
(cherry picked from commit b92b3206e7)
* scd/app-nks.c (find_fid_by_keyref): Disable the cache for now.
(readcert_from_ef): Considere an all zero certificate as not found.
(do_sign): Support ECC and the ESIGN application.
--
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.

* scd/app-nks.c (filelist): Use special value -1 for IDLM pubkeys.
(keygripstr_from_pk_file): Handle special value.
(do_readcert): Ditto.
(do_writecert): Ditto.
--
This allows to get information about the keys from the card. However
the do_readkey still requires a fallback to readcert. This does not
work because there are no certificates yet on the card. The fix is to
fully implement do_readkey.

* g10/pkclist.c (select_algo_from_prefs): Change implicit cipher

Although 3DES is still a compliant algorithm, some other software does
not consider it has compliant but also does not set preference
accordingly. Thus it is better to switch the implicit cipher algorithm
similar to what we already did with SHA-1.
Note that in GnuPG 2.3 3DES is already not anymore used here.

This implements the basic LDAP to WKD mirroring. The blacklist

by using a configuration like:

This feature allows to fetch keyblock by keyblock from an LDAP server.
This way tools can process and maybe filter each keyblock in a more
flexible way. Here is an example where two keyblocks for one mail
address are returned:
$ gpg-connect-agent --dirmngr
> ks_get --ldap --first <foo@example.org>
[... First keyblock is returned ]
OK
> ks_get --next
[ ... Next keyblock is returned ]
OK
> ks_get --next
