This commit add support to detect if openssl used for testing
supports static ECDH key exchange. Skip the ciphersutes if
openssl doesn't support them.

Since PSK cipher suites do not allow client certificate verification,
PSK test cases should be executed under VERIFY=NO. SUB_VERIFIES is
used to constrain verification option for PSK tests.
With aforementioned change, the latter check of
$VERIFY=YES && $TYPE!=PSK is redundant so it's removed.

With the introduction of PSK_TESTS,
- Either `compat.sh -V NO` or `compat.sh -V YES` runs the PSK tests
- `compat.sh` or `compat.sh -V "NO YES"` runs PSK tests only once

There is no need to provide CA file in PSK. Thus VERIFY is
meaningless for PSK. This change omits the arguments passed to
the client and server for $VERIFY=YES.

Under Ubuntu-22.04, wait command prints out Terminated message.
Therefore server process is handled with identical ways like other
processes in compat.sh. In addition, PROCESS_ID is renamed as
SRV_PID to improve code readability.

These variables were both uses to select the default version of OpenSSL
to use for tests:
- when running compat.sh or ssl-opt.sh directly, OPENSSL_CMD was used;
- when running all.sh, OPENSSL was used.
This caused surprising situations if you had one but not the other set
in your environment. For example I used to have OPENSSL_CMD set but not
OPENSSL, so ssl-opt.sh was failing in some all.sh components but passing
when I ran it manually in the same configuration and build, a rather
unpleasant experience.
The natural name would be OPENSSL, and that's what set in the Docker
images used by the CI. However back in the 1.3.x days, that name was
already used in library/Makefile, so it was preferable to pick a
different one, hence OPENSSL_CMD. However the build system has not been
using this name since at least Mbed TLS 2.0.0, so it's now free for use
again (as demonstrated by the fact that it's been set in the CI without
causing any trouble).
So, unify things and use OPENSSL everywhere. Just leave an error message
for the benefit of developers which might have OPENSSL_CMD, not OPENSSL,
set in their environment from the old days.

Restore compatibiltiy testing against OpenSSL for
(D)TLS versions smaller that 1.2.
. Fix the check for support in OpenSSL for these versions
. For test cases for (D)TLS version smaller than 1.2,
restore the configuration of OpenSSL client/server
with the given TLS version, as it was before #5660
that broke it.

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 is needed to enable TLS 1.0, TLS
1.1 and DTLS 1.0. This also 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).

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,

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
If lsof is not available, wait_server_start uses a fixed timeout,
which can trigger a race condition if the timeout turns out to be too
short. Emit a warning so that we know this is going on from the test
logs.
- Some of the CI machines don't have lsof installed yet, so rely on an sleeping
an arbitrary number of seconds while the server starts. We're seeing
occasional failures with the current delay because the CI machines are highly
loaded, which seems to indicate the current delay is not quite enough, but
hopefully not to far either, so double it.
- While at it, also double the watchdog delay: while I don't remember seeing
much failures due to client timeout, this change doesn't impact normal
running time of the script, so better err on the safe side.
These changes don't affect the test and should only affect the false positive
rate coming from the test framework in those scripts.
