ECJPAKE_C only needs MD_LIGHT and it allready auto-enables it in
config_adjust_legacy_crypto.h, so nothing to check here.

We're already making sure of that in

double-check here.

After this change, check_config.h does not have any #defined except:
- the standard header double-inclusion guard
- short-lived helpers that are #undef-ed in the same paragraph

Those were only used for KEY_EXCHANGE_ECJPAKE, but had a much larger
scope than needed. We actually don't need those macros if we distinguish
between cases when expressing dependencies for this key exchange.
The remaining helper macros are all short lived.

It always uses MD now. (The "fall back" to PSA Crypto was only in the
1st iteration of driver-only hash support, before we changed the
architecture to make everything go through MD.)

None of the TLS code is calling low-level hash functions directly. So
the correct dependencies here are MD_CAN.
(I checked and this was the only occurrence.)

Simplify: let's take advantage of the MD_CAN macros instead of doing it
again ourselves.
Fix: SHA-3 was forgotten.

Similarly to check_config.h, also build_info.h should consider
MBEDTLS_PSA_CRYPTO_CLIENT as the define which signals that PSA
Crypto APIs feature are being required in the build (possibly
due to the client/service architecture). It is automatically
enabled if CRYPTO_C is enabled, but only at config_adjust_legacy_crypto.h
which happens after the inclusion of the config_psa.h is needed

When check_config needs to evaluate the availability of a feature
through a PSA API, it should look for MBEDTLS_PSA_CRYPTO_CLIENT
instead of MBEDTLS_PSA_CRYPTO_C, to be able to cover the case
where the API is provided through a client/service interface.

The only real contraint on the raw buffer is that it is large
enough to contain 2 coordinates. Larger buffers are therefore
allowed and the extra data will simply be ignored.
Note = trying to impose a strict sizing on the raw buffer causes
several failures in test suites. This suggests that it is
quite common to use larger buffer to store raw signatures.

Allow the function to support DER buffers than what it is nominally
required by the provided coordinates. In other words let's ignore
padding zeros in the raw number.

The test code to construct test keys and the implementation had matching
errors: both assumed that there was a PSA public key object. Fix this.

In the MBEDTLS_PK_OPAQUE, have mbedtls_pk_get_psa_attributes() require the
specified usage to be enabled for the specified key. Otherwise the following
call to mbedtls_pk_import_into_psa() is unlikely to result in a key with a
useful policy, so the call to mbedtls_pk_get_psa_attributes() was probably
an error.
Adjust the existing test cases accordingly and add a few negative test
cases.

Due to the scope reduction for
mbedtls_ssl_read_early_data(), on
server as early data state variable
we now only need a flag in the
handshake context indicating if
the server has accepted early data
or not.

This reverts commit 0883b8b625.
Due to the scope reduction of mbedtls_ssl_read_early_data()
it is not necessary anymore to refine the usage
of early_data_status/state rather the opposite.

Do not progress the handshake in the API, just
read early data if some has been detected by
a previous call to mbedtls_ssl_handshake(),
mbedtls_ssl_handshake_step(),
mbedtls_ssl_read() or mbedtls_ssl_write().

Introduce early_data_state SSL context field to
distinguish better this internal state from
the status values defined for the
mbedtls_ssl_get_early_data_status() API.
Distinguish also between the client and
server states. Note that the client state
are going to be documented and reworked
as part of the implementation of
mbedtls_ssl_write_early_data().

MBEDTLS_SSL_EARLY_DATA implies

MBEDTLS_SSL_PROTO_TLS1_3 && MBEDTLS_SSL_EARLY_DATA
