to avoid change in behaviour.

Add new mbedtls_pkcs12_pbe_ext function to replace
old mbedtls_pkcs12_pbe function that have security
issues.

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out of date.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.

Fix defined but not used warning when
MBEDTLS_USE_PSA_CRYPTO, MBEDTLS_PK_HAVE_RFC8410_CURVES
and MBEDTLS_PK_HAVE_ECC_KEYS are defined but not
MBEDTLS_PEM_WRITE_C.

We only support ECB and CBC modes for DES. Those two modes require
both encrypt and decrypt directions, so we don't consider DES with
CIPHER_ENCRYPT_ONLY.

Fix unused variable when MBEDTLS_SSL_PROTO_TLS1_3 and
MBEDTLS_SSL_SESSION_TICKETS are enabled but not MBEDTLS_DEBUG_C.

* 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>

#
psa_utils_internal.h was broken out of mbedtls/psa_utils.h, which in
some places were included as <mbedtls/psa_utils.h>. But since
psa_utils_internals.h should be internal, we should not rely on the
system include paths. I suspect a regexp replace gone slightly wrong.
