This is a fix for #722. It updates the client simulation data from
the SSLlabs API. As usual data was pulled, resorted and clients
to display were hand-selected.
Wishlist: Missing is Oreo, OpenSSL 1.1.1, Safari on OX 11, Firefox

With the recent PR #1033 from @dcooper it can also show TLS 1.3
handshakes.
When performing client simulations in "--ssl-native" mode, provide the client's list of supported curves to "$OPENSSL s_client" in order to make the results even more accurate.
This PR improves client simulation in "--ssl-native" mode:
* It changes ${protos[i]} to list the protocols that should be disabled rather than those that should be enabled, except in the case that the client only supports one protocol.
* It sets the values for ${tlsvers[i]}, which is used in run_client_simulation(), but was not defined.
* It adds a new variable, ${ciphersuites[i]}, that lists the TLSv1.3 cipher suites supported by a client.
Client simulation still produces false results in "--ssl-native" mode, but the results are better than before.
This PR fixes the issue raised in #1013. It primarily does this in two ways:
* In calls to `$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.
Support for X448 was recently added to the development branch of OpenSSL 1.1.1. This PR adds an X448 key pair to etc/tls_data.txt (that was generated using OpenSSL 1.1.1) and adds X448 to the supported_groups extension for TLS 1.3 ClientHello messages.
This prime appears to be not only in HAProxy 1.5 but as well in the newer versions. The test result will return incorrect response message, when testing on the newer HAProxy versions (ie. 1.5 is detected but 1.8 is installed).
This PR adds support for TLSv1.3 to run_server_preference(). It only provides partial support, as it only works if the support supports and earlier TLS protocol (in order to determine whether the server has a cipher order). It also will only show TLSv1.3 as the "Negotiated protocol" if $OPENSSL supports TLSv1.3.
This PR also fixes a bug in which the variable "proto" was defined as used as both a regular variable and as an array.
In the data provided by https://api.dev.ssllabs.com/api/v3/getClients, Chrome 57 Win 7 and Firefox 53 Win 7 send ClientHellos that indicate support for TLSv1.3 draft 18, but the highest_protocol for each of these is specified as 0x0303. The result is that if the server being tested supports TLSV1.3 draft 18, `run_client_simulation()` will incorrectly report "No connection" for these servers since the DETECTED_TLS_VERSION (0x0304) will be higher than the specified highest_protocol.
This PR fixes the problem by changing the highest_protocol to 0x0304. Note that another solution to this problem would be to change the ClientHello messages for these two browsers. It is my understanding that TLSv1.3 is disabled by default for these browsers, so presumably the ClientHello messages would not specify TLSv1.3 support if they were configured with TLSv1.3 support disabled.
A PR was just accepted into the master branch of https://github.com/openssl/openssl that specifies OpenSSL names for the ARIA GCM cipher suites: bc32673869. This PR adds these OpenSSL names to the cipher-mapping.txt file. It also changes the description of the encryption algorithm for these ciphers from "ARIA" to "ARIAGCM" to be consistent with OpenSSL and with the other GCM ciphers in the cipher-mapping.txt file.
In addition, OpenSSL names for some of the ARIA CBC ciphers are provided in https://github.com/openssl/openssl/blob/master/doc/man1/ciphers.pod, and this PR adds those OpenSSL names to the cipher-mapping.txt file as well.
Update `$TLS12_CIPHER` to contain only 128 ciphers (so that it will work with servers that can't handle larger ClientHello messages), and also add some newer ciphers to `$TLS12_CIPHER`. Also define a `$TLS12_CIPHER_2ND_TRY` containing a list of 127 ciphers that do not appear in `$TLS12_CIPHER`. `$TLS12_CIPHER_2ND_TRY` is used in `run_protocols()` in order to perform a second test against servers that do not establish a TLSv1.2 connection when offered `$TLS12_CIPHER`.
There is a tab on the line for SSL_CK_RC2_128_CBC_WITH_MD5. When testssl.sh is called with "-E" and "--show-each," this causes the string "not a/v" to be printed two characters to the right of the same string on every other line (at least on Linux systems). This PR just deletes the tab character.
