This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.

This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf.  Other
configured keyservers are ignored.

Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key.  This is currently supported for OpenPGP
cards and certain PKCS#15 cards.
