scd: Use canonical curve name of libgcrypt.

* scd/app-openpgp.c (send_key_attr): Use curve instead of OID.
(ecdh_params): New.
(ecc_read_pubkey): Use ecdh_params.  Use curve name.
(ecc_writekey): Likewise.
(ecc_curve): Rename from ecc_oid.
(parse_algorithm_attribute): Use ecc_curve.
* g10/call-agent.c (learn_status_cb): Use openpgp_is_curve_supported to
intern the curve name string.
* g10/card-util.c (card_status): Conver curve name to alias for print.

Now, sdcaemon answer for KEY-ATTR is in the canonical curve name
instead of the alias.  Since it is used of key generation for
card encryption key with backup, it should be canonical name.
