There are a couple of old SSLv2 ciphers which haben't been included in
etc/cipher-mapping.txt . This PR updates the file. Names were derived
from the (old) OpenSSL / SSLeay source code.
In addition TLS_NULL_WITH_NULL_NULL (>=SSLv3 cipher) was added.
ToDo: Review functions to be updated to use those ciphers.
This PR fixes the issue raised in #1013. It primarily does this in two ways:
* In calls to `$OPENSSL s_client` that specify ciphers, the TLSv1.3 ciphers are provided separately using the `-ciphersuites` option. Then, the `s_client_options()` function manipulates the command-line options as necessary based on the version of OpenSSL being used.
* Calls to `$OPENSSL ciphers` were replaced with calls to `actually_supported_ciphers()`, which calls `$OPENSSL ciphers`. `actually_supported_ciphers()` modifies the parameters for the call to `$OPENSSL ciphers` as necessary, based on the version of OpenSSL being used.
A PR was just accepted into the master branch of https://github.com/openssl/openssl that specifies OpenSSL names for the ARIA GCM cipher suites: bc32673869. This PR adds these OpenSSL names to the cipher-mapping.txt file. It also changes the description of the encryption algorithm for these ciphers from "ARIA" to "ARIAGCM" to be consistent with OpenSSL and with the other GCM ciphers in the cipher-mapping.txt file.
In addition, OpenSSL names for some of the ARIA CBC ciphers are provided in https://github.com/openssl/openssl/blob/master/doc/man1/ciphers.pod, and this PR adds those OpenSSL names to the cipher-mapping.txt file as well.
