Same intended semantics, no casts.
Limitation: this doesn't work on architectures where
sizeof(uintptr_t) < sizeof(void*), which is somewhat weird but possible if
pointers contain redundant information.

The user data is typically a pointer to a data structure or a handle which
may no longer be valid after the session is restored. If the user data needs
to be preserved, let the application do it. This way, it is a conscious
decision for the application to save/restore either the pointer/handle
itself or the object it refers to.

In structure types that are passed to user callbacks, add a field that the
library won't ever care about. The application can use this field to either
identify an instance of the structure with a handle, or store a pointer to
extra data.

Provide an additional pair of #defines, MBEDTLS_SHA256_USE_A64_CRYPTO_IF_PRESENT
and MBEDTLS_SHA256_USE_A64_CRYPTO_ONLY. At most one of them may be
specified. If used, it is necessary to compile with -march=armv8-a+crypto.
The MBEDTLS_SHA256_PROCESS_ALT and MBEDTLS_SHA256_ALT mechanisms
continue to work, and are mutually exclusive with A64_CRYPTO.
There should be minimal code size impact if no A64_CRYPTO option is set.

These fields need to be enabled for 1.3 even if MBEDTLS_USE_PSA_CRYPTO isn't (1.3 should always use PSA).

Initially this function was doing something because the output format of
psa_export_public() didn't match the ECPoint format that TLS wants.
Then it became a no-op then the output format of psa_export_public()
changed, but it made sense to still keep the function in case the format
changed again. Now that the PSA Crypto API has reached 1.0 status, this
is unlikely to happen, so the no-op function is no longer useful.
Removing it de-clutters the code a bit; while at it we can remove a
temporary stack buffer (that was up to 133 bytes).
It's OK to remove this function even if it was declared in a public
header, as there's a warning at the top of the file saying it's not part
of the public API.

Relying on a PSA_VENDOR macro is not ideal, since the standard doesn't
guarantee this macro exists, but OTOH relying on
MBEDTLS_ECP_DP_xxx_ENABLED was even less ideal, so I believe this is
still an improvement.

We had ECC then PK then ECC, move PK to the end, now all ECC things are
together. (The comments suggest that was the intention all along.)

PKCS5 depends on MD, but is missing a config check resulting in
obscure errors on invalid configurations.

At the end of the benchmark program, heap stats are printed, and these
stats will be wrong if we reset counters in the middle.
Also remove the function to reset counters, in order to encourage other
programs to behave correctly as well.
