Provide an additional pair of #defines, MBEDTLS_SHA512_USE_A64_CRYPTO_IF_PRESENT
and MBEDTLS_SHA512_USE_A64_CRYPTO_ONLY. At most one of them may be
specified. If used, it is necessary to compile with -march=armv8.2-a+sha3.
The MBEDTLS_SHA512_PROCESS_ALT and MBEDTLS_SHA512_ALT mechanisms
continue to work, and are mutually exclusive with SHA512_USE_A64_CRYPTO.
There should be minimal code size impact if no A64_CRYPTO option is set.
The SHA-512 implementation was originally written by Simon Tatham for PuTTY,
under the MIT licence; dual-licensed as Apache 2 with his kind permission.

MBEDTLS_HAVE_TIME is documented as: "System has time.h and time()."
If that is not defined, do not attempt to include time.h.
A particular problem is platform-time.h, which should only be included if
MBEDTLS_HAVE_TIME is defined, which makes everything messier. Maybe it
should be refactored to have the check inside the header.

Extend mbedtls_ssl_set_hs_own_cert() to reset handshake cert list
if cert provided is null. Previously, mbedtls_ssl_set_hs_own_cert()
only provided a way to append to the handshake certificate list,
without providing a way to replace the handshake certificate list.

Perform the following optimizations:
- fix used flags for conditional compilation
- remove redundant N variable
- move loop used to generate valid k value to helper function
- fix initial value of status
- fix comments

Mention that TLS 1.3 is supported, in addition to (D)TLS 1.2.
Improve and clarify the documentation. In particular, emphasise that the
minor version numbers are the internal numbers which are off by one from the
human numbers.

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.

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