component_test_CID_no_debug was added specifically to be a non-regression
test for https://github.com/Mbed-TLS/mbedtls/issues/3998. Running compat.sh
in the newly introduced config-ccm-psk-dtls1_2.h is also a non-regression
test for that bug. Therefore component_test_CID_no_debug is redundant for
its primary purpose.
Of course every configuration is different, but the additional coverage from
component_test_CID_no_debug is minimal, unlike config-ccm-psk-dtls1_2.h
which is a plausible real-world configuration.
In mbedtls-2.28, component_test_CID_no_debug was never added, and running
the unit tests in that configuration does not trigger the #3998 bug, only
compat.sh does. So, rather than backport component_test_CID_no_debug to
2.28.2, I am removing it from 3.2.

A concurrent branch changes the way the test cases run to no longer use
force_version=tls13, so the automatic version requirement detection will no
longer work after that branch is merged. Therefore, keep the manual
requirement (at least until automatic detection gets smarter).

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.

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).

The added null byte was accounted for twice, once by taking
opt.buffer_size+1 when allocating the buffer and once by taking opt.buffer-1
when filling the buffer. Make opt.buffer_size the size that is actually
read, it's less confusing that way.

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.

The message was removed in 6be9cf542f without
a replacement. A failure would cause the test case to fail anyway, so this
negative check is not really useful.

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.

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.

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

Add accessors to mbedtls_ssl_context: user data, version
ABI-API-checking fails which was expected as this PR adds a new field in mbedtls_ssl_context and mbedtls_ssl_config.
Mention that TLS 1.3 is supported, in addition to (D)TLS 1.2.
Improve and clarify the documentation. In particular, emphasise that the
minor version numbers are the internal numbers which are off by one from the
human numbers.

Same intended semantics, no casts.
Limitation: this doesn't work on architectures where
sizeof(uintptr_t) < sizeof(void*), which is somewhat weird but possible if
pointers contain redundant information.

The user data is typically a pointer to a data structure or a handle which
may no longer be valid after the session is restored. If the user data needs
to be preserved, let the application do it. This way, it is a conscious
decision for the application to save/restore either the pointer/handle
itself or the object it refers to.

In structure types that are passed to user callbacks, add a field that the
library won't ever care about. The application can use this field to either
identify an instance of the structure with a handle, or store a pointer to
extra data.
