ae270bf386 Upgrade the default TLS hash and curve selection, matching X.509
Upgrade the default list of hashes and curves allowed for TLS. The list is
now aligned with X.509 certificate verification: hashes and curves with at
least 255 bits (Curve25519 included), and RSA 2048 and above.

Remove MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE which would no
longer do anything.

Document more precisely what is allowed by default.

e5702489f5 mbedtls_dhm_get_value parameter order: context first, output last
mbedtls_dhm_get_value can be seen as either a copy function or a getter
function. Given the name and the semantics, it's more of a getter, even if
it "gets" by doing a copy. Therefore, put the context first, and the
selector next, leaving the output for last.

d60b6c62d5 Remove per-version ciphersuite configuration API
This commit removes the API

```
    mbedtls_ssl_conf_ciphersuites_for_version()
```

which allows to configure lists of acceptable ciphersuites
for each supported version of SSL/TLS: SSL3, TLS 1.{0,1,2}.

With Mbed TLS 3.0, support for SSL3, TLS 1.0 and TLS 1.1
is dropped. Moreover, upcoming TLS 1.3 support has a different
notion of cipher suite and will require a different API.

This means that it's only for TLS 1.2 that we require
a ciphersuite configuration API, and

```
   mbedtls_ssl_conf_ciphersuites()
```

can be used for that. The version-specific ciphersuite
configuration API `mbedtls_ssl_conf_ciphersuites_for_version()`,
in turn, is no longer needed.

3e3a6789d1 Remove a kludge for the output size of mbedtls_sha512_finish_ret
Remove a kludge to avoid a warning in GCC 11 when calling
mbedtls_sha512_finish_ret with a 48-byte output buffer. This is correct
since we're calculating SHA-384. When mbedtls_sha512_finish_ret's output
parameter was declared as a 64-byte array, GCC 11 -Wstringop-overflow
emitted a well-meaning, but inaccurate buffer overflow warning, which we
tried to work around (successfully with beta releases but unsuccessfully
with GCC 11.1.0 as released). Now that the output parameter is declared as a
pointer, no workaround is necessary.

9cfe6e977d Assert presence of server certificate in Certificate writer
The server-side `Certificate` handshake message writer checks
whether a certificate is present, and if not fails with:

```
   MBEDTLS_ERR_SSL_CERTIFICATE_REQUIRED
```

This should never happen, since the library checks the presence
of a suitable certificate before picking a ciphersuite. It is
therefore more suitable to convert this check into an assertion,
and fail with MBEDTLS_ERR_SSL_INTERNAL_ERROR upon failure.

6c78046960 Remove uses of MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH
The error code MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH is only
returned from the internal function

```
   mbedtls_ssl_set_calc_verify_md()
```

Moreover, at every call-site of this function, it is only
checked whether the return value is 0 or not, while the
exact return value is irrelevant.

The behavior the library is therefore unchanged if we return 1
instead of MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH in
`mbedtls_ssl_set_calc_verify_md()`. This commit makes this change.

91e1cc3bd7 Remove MBEDTLS_ERR_SSL_CERTIFICATE_TOO_LARGE error code
This error is used when the output buffer isn't large enough
to hold our own certificate.

In the interest of cleaning up the error space for 3.0, this commit
removes MBEDTLS_ERR_SSL_CERTIFICATE_TOO_LARGE and replaces its single
use by MBEDTLS_ERR_SSL_BUFFER_TOO_SMALL.

3352a53475 Modify config option for SHA384.
Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.

check_config is the only module which enforces that SHA512 is
enabled together with SHA384.
