ca1e605b9c Merge remote-tracking branch 'upstream-public/development' into development-restricted-merge-20230925
Conflicts:
* `include/mbedtls/build_info.h`: a new fragment to auto-enable
  `MBEDTLS_CIPHER_PADDING_PKCS7` was added in
  c9f4040f7f in `development-restricted`.
  In `development`, this section of the file has moved to
  `include/mbedtls/config_adjust_legacy_crypto.h`.
* `library/bignum.c`: function name change in `development-restricted` vs
  comment change in development. The comment change in `development` is not
  really relevant, so just take the line from `development-restricted`.

9af58cd7f8 New preprocessor symbol indicating that AESNI support is present
The configuration symbol MBEDTLS_AESNI_C requests AESNI support, but it is
ignored if the platform doesn't have AESNI. This allows keeping
MBEDTLS_AESNI_C enabled (as it is in the default build) when building for
platforms other than x86_64, or when MBEDTLS_HAVE_ASM is disabled.

To facilitate maintenance, always use the symbol MBEDTLS_AESNI_HAVE_CODE to
answer the question "can I call mbedtls_aesni_xxx functions?", rather than
repeating the check `defined(MBEDTLS_AESNI_C) && ...`.

e9b55929dc Remove useless platform macro redefinitions: automatic part
Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.

This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')

eab65acca4 bugfix: if the len of iv is not 96-bit, y0 can be calculated incorrectly.
An initialization vector IV can have any number of bits between 1 and
2^64. So it should be filled to the lower 64-bit in the last step

The GET macros used to write to a macro parameter, but now
they can be used to assign a value to the desired variable
rather than pass it in as an argument and have it modified

MBEDTLS_GET_UINT32_LE and was there for replaced in the

5a7be10419 Add output_length parameter to mbedtls_gcm_finish
Without this parameter, it would be hard for callers to know how many bytes
of output the function wrote into the output buffer. It would be possible,
since the cumulated output must have the same length as the cumulated input,
but it would be cumbersome for the caller to keep track.
