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`.

e820c0abc8 Update spelling "mbed TLS" to "Mbed TLS"
The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":

```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```

Justification for the omissions:

* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
  occurrences are significant names in certificates and such. Changing
  the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
  updates.

2be8c63af7 Create psa_util_internal.h
Most functions in psa_util.h are going to end up there (except those
that can be static in one file), but I wanted to have separate commits
for file creation and moving code around, so for now the new file's
pretty empty but that will change in the next few commits.

2df73ae742 mbedtls: fix possible false success in ...check_tags() helpers
We should report a error when the security check of the security
tag was not made. In the other case false success is possible and
is not observable by the software.

Technically this could lead to a security flaw.

945b23c46f Include platform.h unconditionally: automatic part
We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.

There should be no change in behavior since just including the header should
not change the behavior of a program.

This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:

```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')
```
