While we are thankful that Ivan Ristic permitted to use the client
data from SSLlabs, it became of bit outdated now (see #1158). Also
as sslhaf [1] was used, the data comes from HTTP traffic only.
This is a start to address it. It provides data from Android 9
(connecting to the play store, so that it is sure we don't capture
a ClientHello from an application having an own TLS stack.
Also it provides documentation how to grab data yourself, and
provide it back to testssl.sh.
Aim is at least for testssl.sh 3.0 to add Android 8 and OpenSSL 1.1.1 (@drwetter).
My hope others can assist with Safari on OSX 11 and 12. Java 10 and 11,
and a recent Opera and Edge version. (Firefox and Chrome are out of
date too)
Mail clients to follow later.

- Darwin doesn't build with -static (removed; file name suffix changed to "dynamic" in this case)
- Darwin has a different openssldir (/private/etc/ssl)
- script doesn't fail any more at make clean step in case there is no Makefile yet
- Darwin 64 bit compilation needs ./Configure instead of ./config and an explicit reference to darwin64-x86_64-cc
https://api.dev.ssllabs.com/api/v3/getClients incorrectly indicates a highestProtocol of 771 (TLS 1.2) for clients that support TLS 1.3, which leads run_client_simulation() to incorrectly report "no connection" if the client would have actually connected using TLS 1.3.
This has been addressed by manually editing etc/client-simulation.txt to set the highest_protocol to 0x0304 for the clients that support TLS 1.3.
This PR modifies update_client_sim_data.pl to automatically apply the fix for clients that support TLS 1.3 in order to avoid a possible regression when etc/client-simulation.txt is updated.
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 fixes a bug which prevented the script from running properly. Also
the commit restores writing a correct comment header. In addition it
adds TLS 1.3 ciphers.
timeout: the TLS ticket check has a timeout, so that early on non-reachable hosts
are determined. If it is running into the timeout, it quits early. The
timeout is configurable via environment e.g. TIMEOUT=16 ./ticketbleed.bash <host>
Also other ports are allowed albeit it probably it is of limited use
Supplying no arg is now more user-friendly
