OpenSSL may be configured to support features such as cipher suites or
protocol versions that are disabled by default. Enable them all: we're
testing, we don't care about enabling insecure stuff. This is not needed
with the builds of OpenSSL that we're currently using on the Jenkins CI, but
it's needed with more recent versions such as typically found on developer
machines, and with future CI additions.
The syntax to do that was only introduced in OpenSSL 1.1.0; fortunately we
don't need to do anything special with earlier versions.
With OpenSSL 1.1.1f on Ubuntu 20.04, this allows SHA-1 in certificates,
which is still needed for a few test cases in ssl-opt.sh. Curiously, this is
also needed for the cipher suite TLS-DHE-PSK-WITH-ARIA-128-GCM-SHA256 (and
no other, including other DHE-PSK or ARIA cipher suites).

- comments about (3)DES were inconsistent (one saying "keep 3DES" and
the other "exclude it")
- we don't have any DES or 3DES ciphersuite anyway, so no need to
exclude them or comment about it
- while at it, fix comment about ARIA: it's in the default config now

The ciphers were originally separated by the version conditions, and the spacing
was retained in case it was required later. It has been decided it would be better
to have an unbroken list in alphabetically order to quickly locate ciphers when
necessary

As anything below (D)TLS 1.2 is no longer supported, checks for the
minor version will always be true, and have therefore been removed

Instead add TLS-RSA-WITH-NULL-SHA256 to list of common ciphersuites.
It therefore has to be removed from GnuTLS as it could then duplicate.

After every edge case to append which ciphers were being used
a call to translate_ciphers.py was being made.
Now a call to translate_ciphers are made at the end of every

3 times. 1 for MBedTLS, GNUTLS and OpenSSL. 1 for MBedTLS and
OpenSSL and another 1 for MBedTLS and GNUTLS.

Our interoperability tests fail with a recent OpenSSL server. The
reason is that they force 1024-bit Diffie-Hellman parameters, which
recent OpenSSL (e.g. 1.1.1f on Ubuntu 20.04) reject:
```
140072814650688:error:1408518A:SSL routines:ssl3_ctx_ctrl:dh key too small:../ssl/s3_lib.c:3782:
```
We've been passing custom DH parameters since
6195767554 because OpenSSL <=1.0.2a
requires it. This is only concerns the version we use as
OPENSSL_LEGACY. So only use custom DH parameters for that version. In
compat.sh, use it based on the observed version of $OPENSSL_CMD.
This way, ssl-opt.sh and compat.sh work (barring other issues) for all
our reference versions of OpenSSL as well as for a modern system OpenSSL.

Fix `printf "$foo"` which treats the value of `foo` as a printf format
rather than a string.
I used the following command to find potentially problematic lines:
```
git ls-files '*.sh' | xargs egrep 'printf +("?[^"]*|[^ ]*)\$'
```
The remaining ones are false positives for this regexp.
The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive
PASS
```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

Replace server2.crt with server2-sha256.crt which, as the name implies, is
just the SHA-256 version of the same certificate.
Replace server1.crt with cert_sha256.crt which, as the name doesn't imply, is
associated with the same key and just have a slightly different Subject Name,
which doesn't matter in this instance.
The other certificates used in this script (server5.crt and server6.crt) are
already signed with SHA-256.
This change is motivated by the fact that recent versions of GnuTLS (or older
versions with the Debian patches) reject SHA-1 in certificates by default, as
they should. There are options to still accept it (%VERIFY_ALLOW_BROKEN and
%VERIFY_ALLOW_SIGN_WITH_SHA1) but:
- they're not available in all versions that reject SHA-1-signed certs;
- moving to SHA-2 just seems cleaner anyway.

ciphersuites were removed from defaults in lib/gnutls_priority.c,
tests/priorities.c.
Since we do want to test the ciphersuites, explicitly re-enable them in the
server's priority string. (This is a no-op with versions of GnuTLS where those
are already enabled by default.)

compat.sh used to skip OpenSSL altogether for DTLS 1.2, because older
versions of OpenSSL didn't support it. But these days it is supported.
We don't want to use DTLS 1.2 with OpenSSL unconditionally, because we
still use legacy versions of OpenSSL to test with legacy ciphers. So
check whether the version we're using supports it.
Limit log output in compat.sh and ssl-opt.sh, in case of failures with these
scripts where they may output seemingly unlimited length error logs.
Note that ulimit -f uses units of 512 bytes, so we use 10 * 1024 * 1024 * 2 to
get 10 GiB.
This is disabled by default since it requires OpenSSL >= 1.1.0 and the current
default version on the CI is 1.0.2. However, the CI also has 1.1.1-rc which
can be used for this.
I'm going to touch the GCM/CCM/CCM-8 code in the next commit, and so far we
didn't have any interop testing for CCM/CCM-8.
Our standard development/testing environment currently has GnuTLS 3.4.10, and
fortunately support for CCM/CCM-8 was introduced in GnuTLS 3.4.0
Support in OpenSSL was introduced in 1.1.0 which is not yet the default
version in the CI.

Disabled by default, needs OpenSSL >= 1.1.1 - tested locally with 1.1.1-pre1
Local version of OpenSSL was compiled with:
./config --prefix=$HOME/usr/openssl-1.1.1-pre1 -Wl,--enable-new-dtags,-rpath,'$(LIBRPATH)'
make
make install
With OpenSSL 1.1.1-pre1, two ciphersuites were incorrectly skipped,
but this has since been fixed in OpenSSL master, see:
https://github.com/openssl/openssl/issues/5406
