The function reset_checksum() can be called more than once with the same
handshake context (this happens with DTLS clients, and perhaps in other
cases as well). When that happens, we need to free the old MD contexts
before setting them up again.
Note: the PSA path was already doing the right thing by calling abort,
we just needed to do the same on the MD path.

With the introduction of #7047, ssl_tls.c uses
mbedtls_md_error_from_psa. This complicates
the dependencies for compiling in psa_to_md_errors,
since now these should be ifdeffed also by
MBEDTLS_USE_PSA_CRYPTO followed by a series of or'ed
MBEDTLS_HAS_ALG_SHA_XXX_VIA_MD_OR_PSA_BASED_ON_USE_PSA.
Since this mechanism will be removed soon, we can simplify it to
just MBEDTLS_USE_PSA_CRYPTO.

GCC 4.6+ complains if a deprecated function calls another.
Working around this universally would require a lot of
preprocessing, this seems to be an easier solution.
Copy mbedtls_pk_error_from_psa code without duplicates
instead of calling the function.

Move all error translation utilities to psa_util.c.
Introduce macros and functions to avoid having
a local copy of the error translating function in
each place.
Identify overlapping errors and introduce a
generic function.
Provide a single macro for all error translations
(unless one file needs a couple of different ones).

Due to a misunderstanding about the purpose of the test, I had limited this to
ECC keys only, however this defeats the purpose of the test, and left gaps in
test coverage.

When MBEDTLS_USE_PSA_CRYPTO is enabled, the application must call
psa_crypto_init() before directly or indirectly calling cipher or PK code
that will use PSA under the hood. Document this explicitly for some
functions.
To avoid clutter, this commit only documents the need to call
psa_crypto_init() in common, non-obvious cases: parsing a public key
directly or via X.509, or setting up an SSL context. Functions that are
normally only called after such a function (for example, using an already
constructed PK object), or where the need for PSA is obvious because they
take a key ID as argument, do not need more explicit documentaion.

Explicitly document that when using TLS 1.3, you must initialize PSA crypto
before starting a handshake.

The split of ssl_handle_hs_message_post_handshake() into
ssl_tls12_handle_hs_message_post_handshake() and
ssl_tls13_handle_hs_message_post_handshake() fixed some user-visible bugs.
Add a changelog entry for those bugs.

This makes no difference when starting from the default configuration. It
allows tls13-only.h to be used with other base configurations such as `full`.

There's no renegotiation in TLS 1.3, so this option should have no effect.
Insist on having it disabled, to avoid the risk of accidentally having
different behavior in TLS 1.3 if the option is enabled (as happened in
https://github.com/Mbed-TLS/mbedtls/issues/6200).
