Make sure that buf always has enough room for what it will contain. Before,
this was not the case if the buffer was smaller than the default response,
leading to memory corruption in ssl_server2.

Some DTLS reordering tests rely on certificate authentication messages. It
is probably possible to adapt them to rely on different messages, but for
now, skip them in PSK-only builds.

If MBEDTLS_SSL_EXTENDED_MASTER_SECRET is disabled or the feature is disabled
at runtime, and if client authentication is not used, then calc_verify is not
called, so don't require the corresponding debug trace.

When doing builds with PSA enabled or with debug traces enabled, convey this
in $MBEDTLS_TEST_CONFIGURATION and in the terminal logs.
This fixes a bug that the outcome file did not distinguish entries from
test cases run in a reference configuration with or without PSA.

User-visible changes:
* With no argument, configurations are now tested in a deterministic order.
* When given arguments, configurations are now tested in the order given.
* When given arguments, if the same configuration is passed multiple times,
it will now be tested multiple times.

Many test cases in ssl-opt.sh need error messages (MBEDTLS_ERROR_C) or SSL
traces (MBEDTLS_DEBUG_C). Some sample configurations don't include these
options. When running ssl-opt.sh on those configurations, enable the
required options. They must be listed in the config*.h file, commented out.
Run ssl-opt in the following configurations with debug options:
ccm-psk-tls1_2, ccm-psk-dtls1_2, suite-b. Skip mini-tls1_1 for now because
it requires significant improvements to ssl-opt.sh (lots of missing
requires_xxx).

In a PSK-only build:
* Skip tests that rely on a specific non-PSK cipher suite.
* Skip tests that exercise a certificate authentication feature.
* Pass a pre-shared key in tests that don't mind the key exchange type.
This commit only considers PSK-only builds vs builds with certificates. It
does not aim to do something useful for builds with an asymmetric key
exchange and a pre-shared key for authentication.

These tests ensure that a certain cipher suite is in use, so they fail in
builds that lack one of the corresponding algorithms.

Skip tests that require a specific version of the protocol if that version
is disabled at compile time.
This commit only partially does the job, mostly covering tests that check
the protocol version in client or server logs. It is not intended to be
exhaustive; in particular many uses of force_version are not covered (I
think they should instead be covered automatically, but this is out of scope
of the current commit).

Since MBEDTLS_TIMING_C is enabled, mbedtls_entropy_init() adds the weak
source MBEDTLS_ENTROPY_MAX_SOURCES(). With mbedtls_platform_entropy_poll(),
this makes two sources. The unit tests need room for a third source.

1. Copy config-ccm-psk-tls1_2.h
2. Add DTLS support
3. Add some TLS and DTLS features that are useful in low-bandwidth,
low-reliability networks
4. Reduce the SSL buffer to a very small size

time() is only needed to seed the PRNG non-deterministically. If it isn't
available, do seed it, but pick a static seed.

Having such implementation might cause issues for those that
expect to have a working implementation.
Having a compile-time error is better in such case.

Encrypt-Then-Mac (ETM) is supported in Mbed TLS
server for TLS version geater than SSLv3 and only
for the CBC cipher mode thus make it
clear in the SSL context.
The previous code was ok as long as the check of
the ETM status was done only in the case of the CBC
cipher mode but fragile as #5573 revealed.
