Automatically detect when an mbedtls or openssl client enables fallback
SCSV.
For test cases with a hard-coded ClientHello with FALLBACK_SCSV, declare the
dependency manually. Remove the erroneous requirement on openssl in these
test cases.

When the client or server uses a specific protocol version, automatically
require that version to be enabled at compile time.
An explicit call is still needed in test cases that require a specific
protocol version (due to analyzing version-specific behavior, or checking
the version in logs), but do not force that specific protocol version, or that
force a specific version only on the openssl/gnutls side.

Rename maybe_requires_ciphersuite_enabled() to detect_required_features()
and refactor its code a little. No intended behavior change. In subsequent
commits, this function will detect other requirements in a similar way.

The automatic ciphersuite detection deliberately doesn't operate on test
cases that verify that the test suite is rejected, but some RC4 test cases
only apply to configurations where the algorithm must be enabled at compile
time (otherwise the connection would fail in a different way).

Don't depend on the default sizes in the test programs: pass explicit
request and buffer sizes.
Don't depend on MAX_CONTENT_LEN (other than it not being extremely small:
this commit assumes that it will never be less than 101).

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).

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

The timing module might include time.h on its own when on

To be able to test utility programs for an absence of time.h, we need a

baremetal compiles should not include time.h, as MBEDTLS_HAVE_TIME is
undefined. To test this, provide an overriding include directory that
has a time.h which throws a meaningful error if included.

Expand abi_check.py to look for backward incompatibilities not only in
the interface exposed to application code (and to some extent driver
code), but also to the interface exposed via the storage format, which
is relevant when upgrading Mbed TLS on a device with a PSA keystore.
Strictly speaking, the storage format checks look for regressions in
the automatically generated storage format test data. Incompatible
changes that are not covered by the generated tests will also not be
covered by the interface checker.
A known defect in this commit is that the --brief output is not brief
for storage format checks.

In build_arm_none_eabi_gcc_m0plus, use baremetal_size instead of baremetal
as the configuration, i.e. exclude debugging features. This job is the only
one switching to baremetal_size because it's our primary point of reference
for code size evolution, and which is the only job where we display the code
size built with -Os so it's presumably the only job for which we really care
about a meaningful code size report.
