* tests/bench-slope.c (bench_pk_algo, bench_pk_operation, bench_pk_oper)
(bench_pk_hd, sample_private_rsa_key_2048, sample_public_rsa_key_2048)
(sample_private_rsa_key_3072, sample_public_rsa_key_3072)
(sample_private_rsa_key_4096, sample_public_rsa_key_4096)
(sample_private_dsa_key_2048, sample_public_dsa_key_2048)
(sample_private_dsa_key_3072, sample_public_dsa_key_3072, pk_algos)
(pk_algo_name, pk_map_name, bench_pk_init, bench_pk_free)
(bench_pk_sign_do_bench, bench_pk_verify_do_bench, pk_sign_ops)
(pk_verify_ops, pk_operations, cipher_pk_one, _pk_bench, pk_bench): New.
(print_help): Add mention of 'pk'.
(main): Add "pk" tests.
--
Only ECC and post-quantum algorithms had slope benchmarking, so RSA and
DSA signing and verification were covered by 'benchmark' alone.
Keys are samples instead of being generated, because prime search time
varies too much for slope measurement to give stable result. Signing
repetitions are scaled down per key size, as RSA-4096 signing alone
would otherwise take longer than rest of the section.
