This commit lands full ECDSA key support when using the OpenSSL backend. Which includes: New KEX methods: ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521 Can now read OpenSSL formatted ECDSA key files. Now supports known host keys of type ecdsa-sha2-nistp256. New curve types: NID_X9_62_prime256v1, NID_secp384r1, NID_secp521r1 Default host key preferred ordering is now nistp256, nistp384, nistp521, rsa, dss.
