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 providing proof of possession of
an RSA private key, allow the usage for RSA
PSS signatures of a hash with a security
level lower that the security level of the
RSA private key.
We did not allow this in the first place to
align with the ECDSA case. But as it is not
mandated by the TLS 1.3 specification (in
contrary to ECDSA), let's allow it.

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.

As a public header, it should no longer include common.h, just use
build_info.h which is what we actually need anyway.

gcm.c had a slightly different pattern for the conditional inclusion of
platform.h which didn't fit the general replacement. Simplify it manually.

Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.
This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')

Some source files included platform.h in a nested conditional. The previous
commit "Include platform.h unconditionally: automatic part" only removed
the outer conditional. This commit removes the inner conditional.
This commit once again 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"')
```

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"')

TLS uses it to derive the session secret. The algorithm takes a serialized
point in an uncompressed form, extracts the X coordinate and computes
SHA256 of it. It is only expected to work with P-256.
