This both simplifies parsing a little, and suppresses warnings. Suppressing
warnings is both good and bad: on the one hand it resolves problems such as
https://github.com/Mbed-TLS/mbedtls/issues/5731, on the other hand it may
hide clues as to why lsof wouldn't be working as expected.

When ARC4 ciphersuites are compiled in, but removed from the default list,
requires_ciphersuite_enabled does not consider them to be enabled. Therefore
test cases for MBEDTLS_REMOVE_ARC4_CIPHERSUITES, which must run in such
configurations, must not use requires_ciphersuite_enabled.
Instead, require the corresponding cryptographic mechanisms. In addition,
for the test case "RC4: both enabled", bypass the automatic ciphersuite
support detection based on force_ciphersuite= that would otherwise cause
this test case to be skipped. (This automatic detection doesn't cause the
negative tests to be skipped because it has an exception whenthe handshake
is supposed to fail.)

USE_PSA_DONE() already checks that there are no used key slots.
The call to TEST_ASSERT() wouldn't have worked properly on failure anyway,
since it would jump back to the exit label.

`curves.pl` (invoked by `all.sh test_depends_curves`, and
`all.sh test_depends_curves_psa`) currently runs two series of tests:
* For each curve, test with only that curve enabled.
* For each curve, test with all curves but that one.
Originally this script was introduced to validate test dependencies, and for
that all-but-one gives better results because it handles test cases that
require multiple curves. Then we extended the script to also test with a
single curve, which matches many real-world setups and catches some product
bugs. Single-curve testing also validates test dependencies in a more
limited way.
Remove all-but-one curve testing, because it doesn't add much to the test
coverage. Mainly, this means that we now won't detect if a test case
declares two curve dependencies but actually also depends on a third. This
is an acceptable loss.
The trigger for removing all-but-one curve testing is that this will make
the job take only about half as long, and the length of the job was a bit of
a problem. Resolves#5729.

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.

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).

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.

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).

We don't yet support all combinations of configurations. With all.sh as it
currently stands, component_test_psa_crypto_config_accel_cipher results in a
build where PSA_WANT_ALG_CMAC is disabled but CMAC operations succeed
nonetheless, going via the driver. With the systematic testing of
not-supported operations, this now results in a test failure.
The code in all.sh does not respect the principle documented in
df885c052c:
> The PSA_WANT_* macros have to be the same as the ones
> used to build the Mbed TLS library the test driver
> library is supposed to be linked to as the PSA_WANT_*
> macros are used in the definition of structures and
> macros that are shared by the PSA crypto core,
> Mbed TLS drivers and the driver test library.
Disable PSA_WANT_ALG_CMAC completely in this test component. This is not
wrong and it makes the test component pass.
