ecc: Simply use unsigned int for cofactor, not MPI.
* cipher/ecc-common.h (elliptic_curve_t): Use unsigned int for H.
* src/ec-context.h (struct mpi_ec_ctx_s): Ditto.
* cipher/ecc-curves.c (ecc_domain_parms_t): Ditto.
(domain_parms): Update for the cofactors.
(_gcry_ecc_fill_in_curve): H is no longer MPI, but unsigned int.
(_gcry_ecc_get_curve): Remove handling for H.
(_gcry_mpi_ec_new): In KEYPARM, cofactor is still MPI.
(_gcry_ecc_get_param_sexp): H is no longer MPI, but unsigned int.
(_gcry_ecc_get_mpi): Keep the API, returning MPI for "h".
(_gcry_ecc_set_mpi): Likewise.
* cipher/ecc-ecdh.c (_gcry_ecc_mul_point): Fix for unsigned int.
* cipher/ecc-eddsa.c (_gcry_ecc_eddsa_genkey): Likewise.
* cipher/ecc-misc.c (_gcry_ecc_curve_free): Likewise.
* cipher/ecc.c (nist_generate_key, test_ecdh_only_keys): Likewise.
(test_ecdh_only_keys, ecc_generate, ecc_check_secret_key): Likewise.
(ecc_sign, ecc_verify, ecc_encrypt_raw, ecc_decrypt_raw): Likewise.
(_gcry_pk_ecc_get_sexp): Likewise.
* mpi/ec.c (ec_deinit): Likewise.
