98b3cd6b23 Remove the sample program aescrypt2
The sample program aescrypt2 shows bad practice: hand-rolled CBC
implementation, CBC+HMAC for AEAD, hand-rolled iterated SHA-2 for key
stretching, no algorithm agility. The new sample program pbcrypt does
the same thing, but better. So remove aescrypt2.

Fix #1906

4d01c5b5c3 Remove dead code from pk_parse_key_pkcs8_unencrypted_der
pk_get_pk_alg will either return 0 or a pk error code. This means that
the error code will always be a high level module ID and so we just
return ret.

456d29c20b Rename mbedtls_error_add_ext to mbedtls_error_add
This function was previously called mbedtls_error_add_ext because there
was a macro called mbedtls_error_add. That later got capitalised which
allows the function to now be named mbedtls_error_add.

Add implementation for MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS

Merging as it has been ready for four days now and I prefer not having to go through other rebases especially given the coming change of scope of development (3.0 rather than 2.2x).

6b0f911b9a Use Python 3 instead of Python 2 to generate test files
Python 2 is no longer officially supported, but we were still using it
to generate test suite .c files from .function files when using GNU
make. Switch to looking for Python 3.

This change was done for CMake a long time ago.

PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG several times, some macros updated

C99 compilers are guaranteed to support.

ce48702448 Get a builtin key's attributes in order to correctly get its size
Leverage the fact that the get_builtin_key entrypoint returns a key's
attributes, such that a proper size for the builtin key's buffer can
be calculated through the driver's get_key_buffer_size hook.

a1ce2f2675 Rename test driver lifetime to location

1a0fbacde1 Refactor opaque key handling in the test driver
Builtin key support for the test driver is always compiled in, and no
  longer guarded by MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS.
Parsing the key slot from the buffer by cast and assign instead of memcmp.
For exporting keys, the test driver no longer reaches into the key
  identifier in order to check whether a key is builtin, but rather
  assumes so based on the key buffer length. It's the driver's
  responsibility to be able to detect the key material it returned as part
  of the get_builtin_key operation.
