gpg: Make Kyber creation more flexible.
* common/openpgp-oid.c (openpgp_is_curve_supported): Allow the abbreviated curve name. * g10/pkglue.c (pk_encrypt): Add debug output. * g10/seskey.c (encode_session_key): Handle Kyber session key like ECDH. This is just a stub. * g10/keygen.c (ecckey_from_sexp): Use the modern OID for cv25519. (parse_key_parameter_part): Allow more Kyber variants.
Test by creating an ed25519 key and using
gpg --quick-add-key --batch --passphrase "" <fingerprint> <algo>
to create several subkeys. Tested with ALGOs:
kyber768 kyber1024 ky768_cv25519 ky768_bp256 kyber768_nistp256 ky1024_cv448
All curves capable of encryption should work.
