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`.
Components that accelerate an algorithm that uses hashing internally
(such as deterministic ECDSA and RSA-PSS) need the hash algorithms
available in libtestdriver1.
Previously, the omission of SHA-3 in
tests/include/test/drivers/crypto_config_test_driver_extension.h meant
it was enabled in libtestdriver1 when not requesting its acceleration,
and disabled when requesting it. Adding it in a previous commit fixed
the components that asked it accelerated, but broke the component that
didn't ask for it but still needed it.
Fix those components by explicitly requesting SHA-3 as we already do for
the other hash algorithms that are require for the same reason.
Note: this broke test_suite_psa_crypto_storage_format.v0 which is
apparently the only place exercising signatures with SHA-3.

Test mbedtls_ssl_decrypt_buf() with a null cipher (the only type of stream
cipher we support). Test the good case (to make sure the test code
constructs the input correctly), test with an invalid MAC, and test with a
shortened input.

test_suite_ssl is huge and needs splitting.
Create a new test suite focused on mbedtls_ssl_decrypt_buf(), which is a
complicated function that needs more thorough testing with malformed inputs.
At this point, we are only doing negative testing with CBC-non-ETM test
suites. This needs to grow.

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.

Move the initialisation of the pkcs7 object to before the first possible
test failure, otherwise failure in those tests could result in an
uninitialised pointer being free'd. Found by coverity.

In make builds, when GEN_FILES is false (empty), don't try to re-generate
configuration-independent source files, regardless of whether they seem
out of date. This is useful, for example, if you have a source tree where
`make generated_files` has already run and file timestamps reflect the
time the files were copied or extracted, and you are now in an environment
that lacks some of the necessary tools to re-generate the files.

* Prevent pkcs12_pbe encryption when PKCS7 padding has been
disabled since this not part of the specs.
* Allow decryption when PKCS7 padding is disabled for legacy
reasons, However, invalid padding is not checked.

security concerns.
* Add tests to check these scenarios. Test data has been
generated by the below code using OpenSSL as a reference:

Conflicts:
* `include/psa/crypto_sizes.h`: the addition of the `u` suffix in this branch
conflicts with the rework of the calculation of `PSA_HASH_MAX_SIZE` and
`PSA_HMAC_MAX_HASH_BLOCK_SIZE` in `development`. Use the new definitions
from `development`, and add the `u` suffix to the relevant constants.
