Both functions are calling mbedtls_cipher_auth_[encrypt/decrypt]_ext() functions. These functions are guarded with MBEDTLS_CIPHER_MODE_AEAD || MBEDTLS_NIST_KW_C flags - make it consistent.
As a result ssl_server2 won't build now with MBEDTLS_SSL_SESSION_TICKETS enabled (mbedtls_cipher_auth_[encrypt/decrypt]_ext() functions not available).
Mark MBEDTLS_SSL_SESSION_TICKETS as dependent on MBEDTLS_CIPHER_MODE_AEAD || MBEDTLS_NIST_KW_C and disable MBEDTLS_SSL_SESSION_TICKETS in stream cipher only build.

Instead of fully validating beforehand
signature algorithms with regards to the
private key, do minimum validation and then
just try to compute the signature. If it
fails try another reasonable algorithm if any.

When selecting the server certificate based on
the signature algorithms supported by the client,
check the signature algorithms as close as possible
to the way they are checked to compute the
signature for the server to prove it possesses
the private key associated to the certificate.
That way we minimize the odds of selecting a
certificate for which the server will not be
able to compute the signature to prove it
possesses the private key associated to the
certificate.

CMakeLists.txt was calling generate_psa_tests.py and siblings to list the
generated test data files with a --directory option, intended the output to
be this argument textually. This used to work, but no longer does, because
the --directory argument is relative to the current directory when the
Python script is invoked, and the script now shows an absolute path.
CMakeLists.txt now completely ignores the directory part of the listed data
file paths and builds its own. The base_xxx_files variables now contain
actual base names, without a "suites/" prefix. This makes it more robust
with respect to the behavior of the Python script, but it will break if
we put data files in multiple different directories one day.

When pylint runs in parallel, it loses the ability to detect duplicated code
across modules. Duplicated code is usually a bad thing, so give pylint the
opportunity to let us know.
This makes pylint slightly slower, but going from 2 threads to 1 does not
make it anywhere close to twice as slow. On my machine, with Python 3.5,
pylint -j2 takes about 12s while single-threaded pylint takes about 16s
of wall clock time.

Initializing return status variables to CORRUPTION_DETECTED is a second line
of defense in library code in case there's a code path where we forget to
assign to the variable. This isn't useful in test code. In any case, here,
we might as well define the variable at the point of use.
This fixes a build error in configurations with MBEDTLS_ERROR_C and
MBEDTLS_PSA_CRYPTO_C both disabled, because then mbedtls/error.h isn't
included so MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED isn't defined.

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

The test cases use the following MPI values.
The .data file only includes those (a, b) values where a <= b, and gives the
sum unconditionally; the test code exercises a >= b and cond == 0 using these
values. The .data file gives two values for the carry out, which are for when
sizeof(mbedtls_mpi_uint) == 4 or 8.

PSK hash alg of server is sha256. If client send only
tls-aes-256-gcm-384, there is no valid ciphersuite
available, handshake should be abort.

A number of places lacked the necessary dependencies on one of
the used features: MD, key exchange with certificate,
entropy, or ETM.

The same elements are now also used when MBEDTLS_USE_PSA_CRYPTO
is defined and respective SHA / MD5 defines are missing.
A new set of macros added in #6065 is used to reflect these dependencies.

TEST_EQUAL(), has the benefit of outputting the values that don't match,
which can make debugging simpler.
Scope:
- Recently added new test functions
- Checks making sure the test case/data is consistent is out of scope
- Only checks where printing the values is likely to be helpful

MBEDTLS_CMAC_C dependency is ivalid.
"PEM read (unknown encryption algorithm)" needs MBEDTLS_CIPHER_MODE_CBC dependency as
otherwise this test is failing in test_when_no_ciphersuites_have_mac configuration
because mbedtls_pem_read_buffer() returns a different error (MBEDTLS_ERR_PEM_FEATURE_UNAVAILABLE).

- Improve test descriptions
- Add more test cases with return value of 1
- Remove the mbedtls prefix from the test function

This is done to be able to bild test_psa_crypto_config_accel_hash component where MD5 is only available accelerated (PSA_WANT_ALG_MD5 is enabled and MBEDTLS_MD5_C is disabled) but MBEDTLS_USE_PSA_CRYPTO is disabled.
So the build should not attempt to enable pem_pbkdf1.
