067a1e735e tls13: Try reasonable sig alg for CertificateVerify signature
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.

38391bf9b6 tls13: Do not impose minimum hash size for RSA PSS signatures
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.

67ea2543ed tls13: server: Add sig alg checks when selecting best certificate
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.

mbedtls_vsnprintf replacement works like mbedtls_snprintf replacement, so

1be45825ab Remove useless guard around include
Including a header is harmless, so we can include do it unconditionally.

The condition was wrong, should have been USE_PSA || PROTO_TLS1_3. If we
just fixed to condition, then we would need to make sure things like:

    #define MBEDTLS_TLS1_3_MD_MAX_SIZE         PSA_HASH_MAX_SIZE

are also guarded, which is useless (extra defines are harmless) and
annoying, so just remove the condition altogether.

f17f85ef0c Simplify definition of TLS 1.3 MD max size.
Actually this macro is never used in parts that depend on USE_PSA, so
it's always using PSA.

Currently the macro seems a bit redundant, but:
- since it's public we can't remove it;
- and there are plans in the future to make it more precise (actually
the largest hash that matters for TLS 1.3 is SHA-384 now).

a844b4b370 No need to use MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED in tests
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.

e9b55929dc Remove useless platform macro redefinitions: automatic part
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)')

945b23c46f Include platform.h unconditionally: automatic part
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"')
