* 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.
* Document new behaviour, known limitations and possible
security concerns.
* Add tests to check these scenarios. Test data has been
generated by the below code using OpenSSL as a reference:
#include <openssl/pkcs12.h>
#include <openssl/evp.h>
#include <openssl/des.h>
#include <openssl/asn1.h>
#include "crypto/asn1.h"
#include <string.h>

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.
Remove unnecessary "../library" prefix from test suite includes. This
makes the tests repo-agnostic between the mbedtls and psa-crypto repos.

This enables compatibility with older versions of CMake that do not have
the abbreviated switch.

Use CMake's -t option to build only the crypto target. Parameterize the
crypto target to have the right name depending on whether this is Mbed
TLS or PSA Crypto.

Either remove exclusive references to Mbed TLS or accompany them with
references to "PSA Crypto".

They aren't used anywhere.
Keep the command line options of all.sh to avoid breaking any wrapper
scripts that people might have.

None of the tests actually need GNUTLS_LEGACY (3.3.8): GNUTLS (3.4.10)
works.
None of the tests actually need OPENSSL_LEGACY (1.0.1j): OPENSSL (1.0.2g)
works.
