Trying to compile MD_C without any of the hash modules would result in a
bunch of unused parameter warning (hence errors in -Werror builds).
We could silence those warnings by casting the parameters to void, but
still, compiling the module in such a configuration would mean all of
its functions are useless (always returning an error).
Seems better to just document the dependency.

Add a platform function mbedtls_setbuf(), defaulting to setbuf().
The intent is to allow disabling stdio buffering when reading or writing
files with sensitive data, because this exposes the sensitive data to a
subsequent memory disclosure vulnerability.

Also have check_config.h enforce this. And MBEDTLS_SSL_EXPORT_KEYS has been removed,
so no longer mention it.

This was intended as experimental, and we've been saying for a long time
that it's superseded by the "unified driver interface", but we hadn't
documented that inside the Mbed TLS source code. So announce it as
deprecated.

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.

As we have now a minimal viable implementation of TLS 1.3,
let's remove EXPERIMENTAL from the config option enabling

CCM requires one of the 128-bit-block block ciphers to be useful, just like GCM.
GCM and CCM need the cipher module.
ChaChaPoly needs ChaCha20 and Poly1305.

It was used to remove the code used when mbedtls_ecp_mul() received a
NULL RNG parameter. This code is no longer relevant (as the RNG may no
longer be NULL) and will be unconditionally removed in the next commit.

Mbed OS now provides POSIX-like time functions, although not alarm() nor
signal(). It is possible to implement MBEDTLS_TIMING_ALT on Mbed OS, so
we should not artificially prevent this in check-config. Remove the the
check that prevents implementing MBEDTLS_TIMING_ALT on Mbed OS.
Note that this limitation originally was added in the following commit,
although there isn't much context around why the restriction was
imposed: 63e7ebaaa184 ("Add material for generating yotta module"). In
2015, Mbed OS was quite a different thing: no RTOS, no threads, just an
asynchronous event loop model. I'd suppose the asynchronous event loop
model made it difficult before to implement MBEDTLS_TIMING_C on Mbed OS,
but that is no longer the case.
